The novel complex [μ-(NC)-Fe(CN)3(NO)-μ-(CN)-Cu(ept)]n·4nH2O (ept = N-(2-aminoethyl)- propane-1,3-diamine) was obtained by the reaction of Cu(ClO4)2·6H2O with N-(2-amino- ethyl)propane-1,3-diamine and Na2[Fe(CN)5NO]·2H2O in water. This compound was characterized by IR, UV-VIS and EPR spectroscopies and magnetic measurement. Single-crystal X-ray structure analysis revealed that the title complex has a one-dimensional polymeric structure containing hexacoordinate iron(II) with five cyanide ligands (two of them, in trans position, bridging) and one nitrosyl group, and pentacoordinate copper(II) with N-(2-aminoethyl)propane-1,3-diamine and two sites occupied by bridging cyanide ligands. Magnetic investigation revealed a very weak antiferromagnetic interaction between the copper atoms (superexchange interaction parameter J = -1.7(1) cm-1; H = -JSiSi+1) within the chain through the diamagnetic [Fe(CN)5NO]2- ions.

The proligand para-benzenediseleninic acid, (HO2SeC6H4SeO2H) (Figure), is the seleno analog to the commonly used MOF spacer proligand, terephthalic acid. Novel coordination polymers based on this proligand, and Mn(II), Fe(II), Co(II), Ni(II), Cu(II) or Zn(II) metal centers containing auxiliary water molecules, [M(O2SeC6H4SeO2)2(H2O)n], were synthesized. Depending on the reaction conditions, different pure or mixed phases can be produced. Crystal to crystal transformations of the novel coordination polymers were studied with powder X ray diffraction, infrared spectral analysis and thermal gravimetric analysis. These coordination polymers can be dehydrated with subsequent formation of new anhydrous coordination polymer phases. Some of these phases can be rehydrated to lead back to the crystalline starting materials or to new crystalline hydrated phases. We are working on the complete structural characterization of the phases.

Strong Antiferromagnetic Interaction

The X-ray structure, porous and magnetic property of a self-assembled network 1 is described in detail. The single crystal X-ray analysis provides 1 as a three-dimensional network, which contains two-dimensional permanent ring forming nanoscale one-dimensional channels. The inter-replacement of perchlorate and hexafluorophosphate anions in solid 1 proves its porous structure. There is somewhat strong antiferromagnetic interaction (J = −74.1 cm−1) between two copper(II) ions through oxalate bridge and weak antiferromagnetic interaction (J = −5.1 cm−1) through AEP ligand.
