Abstract

The title salt, [V(C9H9N)7]+I- or [V(CNXyl)7]+I- (Xyl is 2,6-dimethylphenyl), crystallized from tetrahydrofuran at low temperatures after reacting (Et4N)+[V(CO)6]-, excess of CNXyl and iodine. The complex cation and the two crystallographically different iodide anions, each located on a different glide plane, are well separated in the crystal structure. The V(CN)7 core of the cation has the form of a distorted monocapped trigonal prism. This compound is of interest as the first isolable homoleptic seven-coordinate vanadium analog of the 18-electron [V(CO)7]+ monocation.
