Synthesis and crystal structure of [V2(μ-S2)2(S2CNEt2)4] · 2CH3Cl
Abstract
[V2(μ-S2)2(S2CNEt2)4] 2CH3Cl was synthesized by the reaction of NaS2CNEt2, Li2S and VOCl3 at room temperature. Crystal data: M= 1061.3, space group Pbca, with the orthorhombic parameters: a=20.123(3), b = 20.485(4)1 c=10.911(3)A, V=4497.7Å3, Z=4, Dc=1.57 g/cm3, Mo Ko radiation (λ=0.71069 Å), μ = 13.2 cm−1, F(000)—2168. Final R = 0.041 and Rw=0.047 for 2288 observed reflections with I>3σ(I). The coordination sphere of each V atom in title compound is a distorted tetragonal prism composed of two bidentate dithiocarbamate and two S21− ligands. The V—V distance is 2.890 Å while the V—S distances fall in the range of 2.422–2.505 Å.
