摘要
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 YbRh2.67 ((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 m (3) over barm for the A and B sites, and 4/mm.m for the X site.
