V(1.42)In(1.83)Mo(15)Se(19)

The structure of the title compound, vanadium indium penta­deca­molybdenum nona­deca­selenide, V(1.42)In(1.83)Mo(15)Se(19), is isotypic with In(2.9)Mo(15)Se(19) [Grüttner et al. (1979 ▶). Acta Cryst. B35, 285–292]. It is characterized by two cluster units Mo(6)Se(i) (8)Se(a) (6) and Mo(9)Se(i) (11)S...

Sumario:The structure of the title compound, vanadium indium penta­deca­molybdenum nona­deca­selenide, V(1.42)In(1.83)Mo(15)Se(19), is isotypic with In(2.9)Mo(15)Se(19) [Grüttner et al. (1979 ▶). Acta Cryst. B35, 285–292]. It is characterized by two cluster units Mo(6)Se(i) (8)Se(a) (6) and Mo(9)Se(i) (11)Se(a) (6) (where i represents inner and a apical atoms) that are present in a 1:1 ratio. The cluster units are centered at Wyckoff positions 2b and 2c and have point-group symmetry [Image: see text] and [Image: see text], respectively. The clusters are inter­connected through additional Mo—Se bonds. In the title compound, the V(3+) cations replace the trivalent indium atoms present in In(2.9)Mo(15)Se(19), and a deficiency is observed on the monovalent indium site. One Mo, one Se and the V atom are situated on mirror planes, and two other Se atoms and the In atom are situated on threefold rotation axes.
