Redetermination of the perovskite-type compound YRh(3)B revealing a Rh deficiency.

ABSTRACT: In contrast with previous structural studies of ytterbium trirhodium boride, YbRh(3)B, that suggest a boron deficiency, the current redetermination of the crystal structure of YbRh(3)B revealed instead a rhodium deficiency with a refined composition of YbRh(2.67 (2))B. In the ABX(3) 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.
