Abstract

Reaction of the elements yields black, lustrous, air insensitive crystals of the subhalides Bi4RuI2 (tetragonal, I4/m, a = 1183.9(2) pm, c = 669.7(2) pm. V = 938.66 ̇ 106 pm3) and Bi4RuBr2 (monoclinic, I112/m, a = 1211.9(2) pm, b = 1072.6(2) pm, c = 663.9(2) pm, y = 91.63(1)°, V = 862.64 ̇ 106pm3). The structures of the homöotypic compounds contain 1[RuBi8/2] strands of face-sharing square antiprisms. Halogen atoms lie above the edges of alternate Bi4 squares. Thereby chemical bonding differs significantly within the two types of Bi4 squares Though the Ru atoms on the central axis of the strand of antiprisms form pairs, extended Hückel calculations give no evidence of Ru-Ru bonds.
