The structure described by Ta3Ru5B2 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 13-coordinate geometry to two equivalent Ru(2), eight equivalent Ru(1), and three equivalent B(1) atoms. In the second Ta site, Ta(2) is bonded in a body-centered cubic geometry to eight equivalent Ru(1) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 8-coordinate geometry to two equivalent Ta(2), four equivalent Ta(1), and two equivalent B(1) atoms. In the second Ru site, Ru(2) is bonded in a distorted body-centered cubic geometry to four equivalent Ta(1) and four equivalent B(1) atoms. B(1) is bonded in a 9-coordinate geometry to three equivalent Ta(1), two equivalent Ru(2), and four equivalent Ru(1) atoms. is represented by the CIF card [CIF]
