- 中文摘要: Bis(2,2'-bipyridine)dioxovanadium(V) trifluoromethanesulfonate, obtained from autooxidation of the corresponding oxovanadium (IV) complex, crystallizes in monoclinic, P2/sub 1//n, with a=15.433(2), b=11.013(2), c=27.423(2).ANG., .beta.=104.79(2). degree., Z=4, R=0.0697, and R/sub w/=0.0821. The complex consists of discrete vanadium(V) complex cations and trifluoromethanesulfonate anions. Each asymmetric unit is composed of a pair of enantiomer molecules. The octahedral vanadium complex ion, having a C/sub 2/ axis, comprises a cis-VO/sub 2/, mean V-O distance of 1.622.plmin.0.007.ANG., and two cis-related 2,2'-bipyridine ligands. The V-N bonds trans to each other are short, with a mean V-N distance of 2.108.plmin.0.010.ANG., while those trans to V=O are somewhat longer, with a mean V-N distance of 2.292.plmin.0.022.ANG.. The coordination geometry of the vanadium cation is very similar to that of [ VO(O/sub 2/)(2,2'-bipyridine)/sub 2/ ] /sup +/.
