Abstract The cluster compounds with d9-d9 magnetic system were investigated because of their magnetic character. Some of the copper(Ⅱ) compounds with terephthalato as bridged unit, [{Cu(bipy)[C6H4(COO)2]}2·H2O]n and [Cu(phen)[C6H4(COO)2]]n, have been synthesized through a solvothermal reaction, and their crystal structures have been determined by X-ray diffraction. Their shape looks like zigzag-chain. In this paper, the molecular vibration spectra of the title complexes have been studied in detail. The middle and far-infrared spectra，and Raman spectra of the compounds have been reported and their assignments have been made experientially. The characteristic carbonyl absorption of terephthalato group at 1 688 cm-1 disappeared while the complexes formed. The characteristic peaks of COO- group were splited into two peaks respectively that appeared at 1 603, 1 574 cm-1(νasCOO) and 1 369, 1 356 cm-1 (νsCOO) in [{Cu(bipy)[C6H4(COO)2]}2·H2O]n, and at 1 614, 1 605 cm-1(νasCOO) and 1 373, 1 344 cm-1(νsCOO) in [Cu(phen)[C6H4(COO)2]]n. The relationship between the structures of the compounds and the spectra has been discussed as well. The coincidence between experiential assignments and the theoretic calculation will be confirmed.
