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.
