Abstract
The new barium copper(I) sulfide tetrathiovanadate(V),Ba2Cu3S2[VS4], w as obtained as a by-product of the reaction of BaS with sulvanite (Cu3 VS4). The compound crystallizes monoclinically in the space group C2/c (No. 15), with four formula units in the unit cell, a = 15.135(2) Ang strom, b = 8.930(1) Angstrom, c = 10.738(2) Angstrom and beta = 133.73 (1)degrees. In the structure, infinite double-chains of condensed CuS4 and VS4 tetrahedra are running along [001]. The barium cations are lo cated between the chains at the centers of tricapped trigonal prisms o f sulfur atoms.
