Abstract

Ternary samples SC2MB6 and ScMB4 (M = Rh, Ir) were synthesized and studied by X-ray powder and single crystal diffraction. The crystal structure of the ternary boride SC2RhB6, Y2ReB6 structure type, Pbam space group, a = 8.9144(8) angstrom, b = 11.2105(10) angstrom, c = 3.4833(3) angstrom, Z = 4, V=348.10(5) angstrom(3), rho =4.917 g cm(-3), mu = 8.216mm(-1) was refined to R=0.0193, wR2 = 0.0518 from single crystal X-ray diffraction data (Bruker SMART 100 CCD diffractometer, 573 reflections with I > 2 sigma(I-o)). The lattice parameters for the isotypic Sc2IrB6 compound are a = 8.9149(18) angstrom, b = 11.211(19) angstrom, c = 3.48367(13) angstrom (X-ray powder diffraction, Image Plate Huber G 670 camera). No evidence of formation of the ternary ScMB4 (M = Rh, Ir) compounds with YReB4 structure type was obtained.
