摘要：The coordination polymer {[Cu(VO)2(C10H8N2)2.5(C2O4)2(OH)2·4H2O]}n has been obtained and characterized on the basis of elemental analysis, by electronic and IR spectra, molecular electrical conductivity and thermal analysis. The electronic spectrum shows the presence of VO(IV) species of C4ν symmetry and Cu (II) in octahedral surrounding. The molar conductivity value in DMSO proves that the heteronuclear oxalate-compound is non-electrolyte. IR spectrum proves the presence of the coordinated 4,4’-dipyridyl and of the oxalate anion as a bisbidentate and bidentate ligand. Thermal analysis shows that decomposition occurs in three steps, the last one being the release of the oxalate chains. Based on these methods, a polymeric structure is proposed.
