Redetermination of the perovskite-type compound YRh₃B revealing a Rh deficiency

R. Makita, K. Tanizawa, K. Tanaka and H. Takei

Abstract: In contrast with previous structural studies of ytterbium trirhodium boride, YbRh₃B, that suggest a boron deficiency, the current redetermination of the crystal structure of YbRh₃B revealed instead a rhodium deficiency with a refined composition of YbRh_2.67 (2)B. In the ABX₃ perovskite-type structure, Yb, B and Rh are located on the A, B and X positions, respectively, with site symmetries of mm for the A and B sites, and 4/mm.m for the X site.
