【Abstract】 The cluster compounds with d⁹-d⁹ magnetic system were investigated beca use of their magnetic character. Some of the copper（Ⅱ） compounds with terep ht halato as bridged unit,[{Cu（bipy）[C₆H₄（COO）₂]}₂·H₂O] n and [Cu（phen）[C₆H₄（COO）₂]] n ,have been synthesized through a solvoth ermal reaction,and their crystal structures have been determined by X-ray dif fraction. Their shape looks like zigzag-chain. In this paper,the mole cular vibration spectra of the title complexes have been studied in detail. The middle and far-infrared spectra,and Raman spectra of the compounds h ave been reported and their assignments have been made experientially. The chara cte ristic carbonyl absorption of terephthalato group at 1 688 cm^-1 disappear ed 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 （ ν as _COO ） and 1 369,1 356 cm^-1 （ ν ^s COO ） in [{Cu（bipy）[C₆H₄（COO）₂]}₂·H₂O] n ,and at 1 614,1 605 cm^-1 （ν^as _COO ） and 1 373,1 344 cm^-1 （ν^s_COO ） in [Cu（phen）[C₆H₄（COO）₂]] n . The relationship between the st ructures of the compounds and the spectra has been discussed as well. The coin cidence between experiential assignments and the theoretic calculation will be c onfirmed.更多还原
