【Abstract】 In this paper,we report the infrared compounds of V 2S 6O 2(CuPph 3) 4(Cu(MeCN)) 2 ·2(CH 2Cl 2)·2(PrOH) 1-, VS 4(CuPph 3) 4Br ·CH 2Cl 2 2- and V 2S 6O 2Cu 6(3-MePy) 6 3-. The infrared spectra absorption of the principal bands of these clusters have been assigned. The ranges of infrared absorption of v as(V-S) and δ(cpc) are structurally characteristic of V-Cu-S heterometallic cluster compounds which are used to investigate the relationship between the structure and infrared vibrational spectra.更多还原
