Complexes containing cis-[(MoO2)-O-V]( ) and cis-[(MoO)-O-V(OH)](2 ) centers

Abstract

Cobaltocene reduction of LMoVIO2(SPh) complexes yielded extremely dioxygen-sensitive cobaltocenium salts of the cis-dioxo-Mo(V) radical anions Cis-[LMoVO2(SPh)]-, while sodium acenaphthalenide reduction of La-MoVIO2(SPh) yielded a complex sodium salt containing [LaMoVO2(SPh)]- [L = hydrotris(3,5-dirnethylpyrazol-1-yl)borate (La), hydrotris(3-isopropylpyrazol-1-yl)borate (Lb), or hydrotris(3,5-dimethyl-1,2,4-triazol-1-yl)borate (Lc)]. Crystals of [CoCp2][LcMoVO2(SPh)]·toluene were orthorhombic, space group Pbca, with a = 17.695(3) Å, b = 19.490(3) Å, c = 21.925(4) Å, V = 7561(2) Å3 for Z = 8. The structure, refined using a full-matrix least-squares procedure and 2269 data, converged with R = ..
