title: Crystal structure of hepta-kis-(2,6-di-methyl-phenyl isocyanide-κC)vanadium(I) iodide.
abstract: The title salt, [V(C9H9N)7](+)I(-) or [V(CNX-yl)7](+)I(-) (Xyl is 2,6-di-methyl-phen-yl), crystallized from tetra-hydro-furan 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 inter-est as the first isolable homoleptic seven-coordinate vanadium analog of the 18-electron [V(CO)7](+) monocation.
