| Popis: | The new barium copper(I) sulfide tetrathiovanadate(V), Ba 2 Cu 3 S 2 [VS 4 ], was obtained as a by-product of the reaction of BaS with sulvanite (Cu 3 VS 4 ). The compound crystallizes monoclinically in the space group C2 c (No. 15), with four formula units in the unit cell, a=15.135(2) A , b=8.930(1) A , c=10.738(2) A and β=133.73(1)°. In the structure, infinite double-chains of condensed CuS 4 and VS 4 tetrahedra are running along [001]. The barium cations are located between the chains at the centers of tricapped trigonal prisms of sulfur atoms. |
