In this article, we describe the preparation of anionic heteronuclear one-dimensional coordination polymers made by dirhodium paddlewheels and tetracyanido-metallatate building blocks. A series of complexes of (PPh4)2n[{Rh2(µ-O2CCH3)4}{M(CN)4}]n (M = Ni (1), Pd (2), Pt (3)) formulae were obtained by reaction of [Rh2(μ-O2CCH3)4] with (PPh4)2[M(CN)4] in a 1:1 or 2:1 ratio. Crystals of 1−3 suitable for single crystal X-ray diffraction were grown by slow diffusion of a dichloromethane solution of the dirhodium complex into a chloroform solution of the corresponding tetracyanido–metallatate salt. Compounds 1 and 2 are isostructural and crystallize in the triclinic P-1 space group, while compound 3 crystallizes in the monoclinic P21/n space group. A detailed description of the structures is presented, including the analysis of the packing of anionic chains and PPh4+ cations.

1D Coordination Polymer

Reaction of a methanolic copper(II) acetate solution with tetrazolyl enol derivatives 2a or 2b leads to the formation of the corresponding lD-coordination polymer 1∞[CuL2] 3a and pseudo 1D-coordination polymer [CuL2]2 3b, respectively. On the contrary, reaction of 2c with methanolic copper(II) acetate solution yields OH-bridged 1D-coordination polymer 1∞[CuL2(MeOH)2 3c. Single-crystal X-ray diffraction of the supramolecular species 3 established unequivocally the structures of the stairlike coordination compounds. Reaction of a methanolic copper(II) acetate solution with amidotetrazole derivative 6 leads to the formation of the lD-coordination polymer 1∞ [CuL2] 7. The structure of 7 has been established by X-ray structure analysis

Coordination polymers with a new rigid ligand 1,3-bis(1,2,4-triazol-1-yl)adamantane (L) were prepared by its reaction with cadmium(II) or silver(I) nitrates. Crystal structure of the coordination polymers was determined using single-crystal X-ray diffraction analysis. Silver formed two-dimensional coordination polymer [Ag(L)NO3]n, in which metal ions are linked by 1,3-bis(1,2,4-triazol-1-yl)adamantane ligands, coordinated by nitrogen atoms at positions 2 and 4 of 1,2,4-triazole rings. Layers of the coordination polymer consist of rare 18- and 30-membered {Ag2L2} and {Ag4L4} metallocycles. Cadmium(II) nitrate formed two kinds of one-dimensional coordination polymers depending on the metal-to-ligand ratio used in the synthesis. Coordination polymer [Cd(L)2(NO3)2]n was obtained in case of a 1:2 M:L ratio, while for M:L = 2:1 product {[Cd(L)(NO3)2(CH3OH)]·0.5CH3OH}n was isolated. All coordination polymers demonstrated ligand-centered emission near 450 nm upon excitation at 370 nm.

The coordination polymers {Mg[Fe(L)(CN)5]}n·0.5nH2O and {MgCu2(CH3COO)6}n [L = bis( N-imidazolyl)methane] have been synthesised. X-ray diffraction revealed that {Mg[Fe(L)(CN)5]}n·0.5nH2O has a one-dimensional neutral chain structure consisting of alternating [Mg(L)2(H2O)2)]2+ species and [Fe(L)(CN)5]2– building blocks, which can be further linked into a three-dimensional supramolecular structure by inter-chain p–p interactions. {MgCu2(CH3COO)6}n has a three-dimensional network with the [MgCu2(CH3COO)6] unit as neutral core extended by Mg–O bonds. Magnetic susceptibility studies on {MgCu2(CH3COO)6}n revealed antiferromagnetic interactions between adjacent Cu(II) ions.

AbstractTwo coordination polymers, [Mn2(μ-O2PPh2)2(η1-O2PPh2)2(η1-HOCH3)2(μ-bpe)2·CH3OH]n (1) and [Mn2(μ-O2PPh2)4(μ-bpe)2]n (2), were assembled in single-pot reactions from [Mn(CH3COO)2·4H2O], Ph2P(O)OK and trans-1,4-bis(4-pyridyl)ethene (bpe). The products were characterized by single-crystal X-ray diffraction, which revealed a one-dimensional metal-organic ladder type in 1 and a two-dimensional rectangular grid type in 2. Both 1 and 2 are constructed from six-coordinate Mn(II) nodes that adopt distorted octahedral (MnN4O2) environments; the adjacent nodes are connected by the μ-bpe linkers in 1 or μ-bpe and μ-O2PPh2 linkers in 2 to form different metal-organic networks. The catalytic property of complex 1 for selective thioether oxidation was also investigated in this work.

The combination of cobalt, 3,5-di-tert-butyldioxolene (3,5-dbdiox) and 1-hydroxy-1,2,4,5-tetrakis(pyridin-4-yl)cyclohexane (tpch) yields two coordination polymers with different connectivities, i.e. a one-dimensional zigzag chain and a two-dimensional sheet. Poly[[bis(3,5-di-tert-butylbenzene-1,2-diolato)bis(1,5-di-tert-butyl-4-oxocyclohexa-2,5-dien-1-yl-3-olato)[μ4-1-hydroxy-1,2,4,5-tetrakis(pyridin-4-yl)cyclohexane]cobalt(III)]–ethanol–water 1/7/5], {[Co2(C14H20O2)4(C26H24N4O)]·7C2H5OH·5H2O} n or {[Co2(3,5-dbdiox)4(tpch)}·7EtOH·5H2O} n , is the second structurally characterized example of a two-dimensional coordination polymer based on linked {Co(3,5-dbdiox)2} units. Variable-temperature single-crystal X-ray diffraction studies suggest that catena-poly[[[(3,5-di-tert-butylbenzene-1,2-diolato)(1,5-di-tert-butyl-4-oxocyclohexa-2,5-dien-1-yl-3-olato)cobalt(III)]-μ-1-hydroxy-1,2,4,5-tetrakis(pyridin-4-yl)cyclohexane]–ethanol–water (1/1/5)], {[Co(C14H20O2)2(C26H24N4O)]·C2H5OH·5H2O} n or {[Co(3,5-dbdiox)2(tpch)]·EtOH·5H2O} n , undergoes a temperature-induced valence tautomeric interconversion.

Supramolecular Isomerism

Supramolecular isomerism for coordination networks refers to the existence of different architectures having the same building blocks and identical stoichiometries. For a given building block, different arrangements can lead to the formation of a series of supramolecular isomers. Two one-dimensional CoIIcoordination polymers based onN,N′-bis(pyridin-3-yl)oxalamide (BPO), bothcatena-poly[[[dichloridocobalt(II)]-bis[μ-N,N′-bis(pyridin-3-yl)oxalamide-κ2N:N′]] dimethylformamide disolvate], {[CoCl2(C12H10N4O2)2]·2C3H7NO}n, have been assembled by the solvothermal method. Single-crystal X-ray diffraction analyses reveal that the two compounds are supramolecular isomers, the isomerism being induced by the orientation of the dimethylformamide (DMF) molecules in the crystal lattice.

The new macrocyclic dicyanoargentate complex Cs(dibenzo-24-crown-8)[Ag(CN)2] has been prepared and studied by means of X-ray diffraction (monoclinic, space group P21/a, with a = 12.730(3), b = 15.443(3), c = 15.323(3) Å, V = 3005(1) Å3, Z = 4, R1 = 0.041; wR2 = 0.048 for 5488 unique reflections with I > 3σ(I)). The lattice consists of complex Cs(db- 24-crown-8)+ cations (as an example of the “wrap-around” structure) and [Ag(CN)2]- anions forming a one-dimensional polymeric structure. The caesium atoms are coordinated with 8 oxygen atoms of the macrocycle and two nitrogen atoms of the dicyanoargentate groups, bonding to the cation on both sides of the crown-ether. It is the first structure of a dibenzo-24-crown-8 complex with a large metal cation such as Cs+.

Two infinite complexes {[Cu2(O2CCH3)4](3-tpt)(CH3OH)2}∞ (1) and {[Cu2(O2CPh)4](3-tpt)(C6H6)1.5}∞ (2) were obtained by reactions of 2,4,6-tris(3′-pyridyl)-1,3,5-triazine (3-tpt) with Cu2(O2CCH3)4 and Cu2(O2CPh)4, respectively, which have been structurally established by single-crystal X-ray diffraction. Complex (1) consists of one-dimensional zig-zag chains in its solid state, which can encapsulate methanol molecules; complex (2) consists of one-dimensional helical chains in its solid state, providing large channels which can selectively enclathrate benzene molecules. (1) crystallizes in the monoclinic space group P21/c with a 8.2892(4), b 22.8479(8), c 16.9258(10) Å, β 99.1480(10)°, V 3164.8(3) Å3, and Z 4; (2) crystallizes in the triclinic space group P1 with a 10.7641(8), b 12.0908(8), c 18.9039(12) Å, α 82.514(3)°, β 85.268(2)°, γ 79.746(4)°, V 2395.9(3) Å3, and Z 2. The inclusion selectivity toward aromatic molecules was discussed.

Orthanilic Acid

Reaction of pyridylcarbaldehyde with taurine or orthanilic acid in the presence of copper salts provided copper complexes (PyC(H)N-CxHy-SO3)CuX with X = chloride, nitrate, acetate, or triflate and CxHy = o-C6H4 or C2H4. All complexes were characterized by single crystal X-ray diffraction and formed either mononuclear water adducts, dimeric complexes, or one-dimensional coordination polymers. Activities in the Chan–Lam coupling of aniline with phenylboronic acid varied by less than a factor of two between catalysts with various anions, supporting previous mechanistic claims that the anion does not participate in the formation of copper–boron intermediates. There is no difference in the performance of a catalyst with an alkyl backbone, indicating that sulfonate dissociation is not part of the catalytic cycle.
