TaRuB crystallizes in the orthorhombic Pmma space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 11-coordinate geometry to two equivalent Ru(2), four equivalent Ru(1), one B(2), and four equivalent B(1) atoms. In the second Ta site, Ta(2) is bonded in a 11-coordinate geometry to two equivalent Ru(2), four equivalent Ru(1), one B(2), and four equivalent B(1) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 9-coordinate geometry to two equivalent Ta(2), four equivalent Ta(1), one B(1), and two equivalent B(2) atoms. In the second Ru site, Ru(2) is bonded in a 10-coordinate geometry to two equivalent Ta(2), four equivalent Ta(1), two equivalent B(1), and two equivalent B(2) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to two equivalent Ta(2), four equivalent Ta(1), one Ru(1), one Ru(2), and one B(1) atom. In the second B site, B(2) is bonded in a 9-coordinate geometry to one Ta(2), two equivalent Ta(1), two equivalent Ru(2), and four equivalent Ru(1) atoms.
