The material described by Pr(OsB)4 is alpha Pu-derived structured and crystallizes in the tetragonal P4_2/n space group. Pr(1) is bonded in a 20-coordinate geometry to eight equivalent Os(1) and twelve equivalent B(1) atoms. Os(1) is bonded in a 4-coordinate geometry to two equivalent Pr(1) and four equivalent B(1) atoms. B(1) is bonded in a 5-coordinate geometry to three equivalent Pr(1), four equivalent Os(1), and one B(1) atom. is represented by the CIF card [CIF]
