Two new coordination polymers constructed with the 1,10-phenanthroline derivative 2-(2-chloro- 6-fluorophenyl)-1H-imidazo[4,5-f][1,10]-phenanthroline (L) and different carboxylates, namely, [Cd2(L)2(1,3,5-BTC)(Cl)]·H2O (1) and [Co2(L)2(1,2,4,5-BTC)(H2O)2] (2), have been synthesized under hydrothermal conditions (1,3,5-BTC = 1,3,5-benzenetricarboxylate anion and 1,2,4,5-BTC = 1,2,4,5-benzenetetracarboxylate anion). Crystal data for 1: C47H25Cd2Cl3F2N8O7, triclinic, space group P¯1, a = 10:1084(5), b = 14:9285(7), c = 15:2930(4)Å , α = 72:1050(10), β = 86:160(2), γ = 79:6000(10)°, V = 2159:88(16) °A3, Z = 2.

Their crystal structures have been determined by singlecrystal X-ray diffraction analyses, and the compounds further characterized by physico-chemical and spectroscopic methods. In 1, each 1,3,5-BTC anion connects five Cd(II) atoms to form a double chain. These chains are extended into 2D supramolecular networks through μ - μ interactions. N-H...Cl, N - H...O and O - H...N hydrogen bonding interactions further stabilize the network of 1. In 2, each 1,2,4,5-BTC anion bridges four Co(II) atoms to yield a chain. μ-μ interactions among adjacent chains result in a 2D supramolecular architecture.

Two new related coordination polymers, namely, [Pb(L)(1,4-ndc)] · 0.5H2O (1) and [Cd(L)(1,4- ndc)] · 0.5H2O (2), where L = 2-(3-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,4- ndc = 1,4-naphthalenedicarboxylate, were synthesized under hydrothermal conditions. Crystal data for 1: C62H36F2N8O9Pb2, monoclinic space group C2/c, a = 15.874(3), b = 19.982(4), c = 16.045(3) Å, β = 94.26(3), V = 5075.3(18) Å3, Z = 4. Crystal data for 2: C62H36Cd2F2N8O9, monoclinic space group P21/n, a = 12.622(2), b = 14.038(3), c = 14.938(3) Å , β = 100.81(2), V = 2600.0(8) Å3, Z = 2. In compound 1, the 1,4-ndc ligands connect the Pb(II) atoms to yield a chain structure. The L ligands are attached on the same side of the chain. The π-π interactions between L ligands of neighboring chains result in a 2D supramolecular architecture of 1. In compound 2, 1,4-ndc ligands link the Cd(II) atoms to generate a layer structure. The L ligands from adjacent layers are paired to furnish strong π-π interactions. Further, these layers are extended into 3D supramolecular architectures through these π-π interactions. The structural differences of 1 and 2 suggest the importance of the metal centers in the construction of the coordination polymers. The luminescent properties of the compounds were also investigated.

Two new coordination polymers, [Pb(L)(1,3-bdc)] ·2.5H2O (1) and [Cu(L)(1,4-bdc)] (2) (L = 2- (4-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline; 1,3-bdc, 1,4-bdc = 1,3- and 1,4-benzenedicarboxylate), have been hydrothermally synthesized and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction.

In coordination chemistry and crystal engineering, many factors influence the construction of coordination polymers and the final frameworks depend greatly on the organic ligands used. The diverse coordination modes of N-donor ligands have been employed to assemble metal–organic frameworks. Carboxylic acid ligands can deprotonate completely or partially when bonding to metal ions and can also act as donors or acceptors of hydrogen bonds; they are thus good candidates for the construction of supramolecular architectures. We synthesized under reflux or hydrothermal conditions two new alkaline earth(II) complexes, namely poly[(1,10-phenanthroline-κ2N,N′)bis(μ-3-phenylprop-2-enoato-κ3O,O′:O)calcium(II)], [Ca(C10H7O2)2(C10H8N2)]n, (1), and poly[(1,10-phenanthroline-κ2N,N′)(μ3-3-phenylprop-2-enoato-κ4O:O,O′:O′)(μ-3-phenylprop-2-enoato-κ3O,O′:O)barium(II)], [Ba(C10H7O2)2(C10H8N2)]n, (2), and characterized them by FT–IR and UV–Vis spectroscopies, thermogravimetric analysis (TGA) and single-crystal X-ray diffraction analysis, as well as by powder X-ray diffraction (PXRD) analysis. Complex (1) features a chain topology of type 2,4 C4, where the Ca atoms are connected by O and N atoms, forming a distorted bicapped trigonal prismatic geometry. Complex (2) displays chains of topology type 2,3,5 C4, where the Ba atom is nine-coordinated by seven O atoms of bridging/chelating carboxylate groups from two cinnamate ligands and by two N atoms from one phenanthroline ligand, forming a distorted tricapped prismatic arrangement. Weak C—H...O hydrogen bonds and π–π stacking interactions between phenanthroline ligands are responsible to the formation of a supramolecular three-dimensional network. The thermal decompositions of (1) and (2) in the temperature range 297–1173 K revealed that they both decompose in three steps and transform to the corresponding metal oxide.

VBr2(N3S2) was synthesized by reaction of VCl2(N3S2) with Me3SiBr. It reacts with PPh4Br in dibromomethane solution to form (PPh4)2[VBr3(N3S2)]2. The compounds were characterized by their IR and 51V NMR spectra. The crystal structure of VBr2(N3S2) was determined by X-ray diffraction (2060 reflexions. R = 0.114). Crystal data: triclinic, space group P1̄, a = 586.4, b = 794.2, c = 744.6 pm. α - 89.25, β - 108.58, γ = 99.67°. Z = 2. The vanadium atoms form planar, six-membered rings wjith the N3S2 groups, with short VN distances (172 and 185 pm). Bromine- bridged dimers are associated via V−N links to form chains in a similar way as in some tetrahalides. The structure is similar to that of VCl2(N3S2), but the chains are rotated by 17° along their axes.

Two new coordination polymers, [Zn(PyHBIm)2(IPA)]•3H2O (1), [Cd(PyHBIm)(IPA)(H2O)2]•2H2O (2), were synthesized under hydrothermal conditions based on 2-(3-pyridyl)benzimidazole (3-PyHBIm) and isophthalic acid (IPA). The complexes were characterized by single crystal X-ray diffraction. They contain simple 1D chains and can be assembled into a 3D network through aromatic π–π stacking interactions and hydrogen bonding interactions. Their luminescent properties were studied in the solid state at room temperature.

AbstractThe reactions of Zn(NO3)2 · 6H2O/CuCl2 · 2H2O and 1,4-bis(1-imidazolyl)benzene (bib)/1,4-bis(1-imidazol-1-ylmethyl)benzene (biyb), carried out under hydrothermal conditions, produced two new coordination polymers [Zn(bib)(HCOO)2 · H2O] (1) and [Cu(biyb)Cl2] (2), respectively, which were characterized by elemental analysis, infrared spectroscopy, thermogravimetric analyses, and single-crystal X-ray diffraction. In complex 1, the ZnII centers are bridged by bib ligands to form a chain, where the adjacent chains are condensed by strong intermolecular O–H · · · O hydrogen-bonding and aromatic π-π stacking interactions to generate a 3D supramolecular structure. In 2, the CuII centers are bridged by biyb ligands to form, again, chains through C–H · · · Cl hydrogen bonds, and these adjacent chains with different orientations are joined to generate a 3D supramolecular structure.

The title compound was obtained by the reaction of PPh4Br, Sb2Se3, and bromine in dichloromethane. Its crystal structure was determined by X-ray diffraction. Crystal data: a = 1249.1(2), b = 1307.8(2), c = 2152.3(4) pm, α = 102.93(2), β = 100.83(2), γ = 100.42(2)°, Z = 2, triclinic, space group P1̄. (PPh4)4Sb8Br28 is isotypic with (PPh4)4Sb8I28. The Sb8Br284- ion can be taken as the association product of eight SbBr3 molecules with four Br− ions. Each Sb atom has a distorted octahedral coordination with three shorter (252 to 274 pm) and three longer (300 to 353 pm) Sb-Br bonds. The octahedra share common edges in two parallel rows of four octahedra each. The arrangement of the 28 bromine atoms corresponds to a section of a closest packing of spheres.
