Th(RuB)2 crystallizes in the orthorhombic Fddd space group. Th(1) is bonded in a 10-coordinate geometry to four equivalent Ru(1) and six equivalent B(1) atoms. Ru(1) is bonded in a 4-coordinate geometry to two equivalent Th(1) and four equivalent B(1) atoms. B(1) is bonded in a 7-coordinate geometry to three equivalent Th(1) and four equivalent Ru(1) atoms.
Th(RuB)2 crystallizes in the orthorhombic Fddd space group. Th(1) is bonded in a 10-coordinate geometry to four equivalent Ru(1) and six equivalent B(1) atoms. All Th(1)-Ru(1) bond lengths are 3.01 Å. There are two shorter (2.87 Å) and four longer (3.07 Å) Th(1)-B(1) bond lengths. Ru(1) is bonded in a 4-coordinate geometry to two equivalent Th(1) and four equivalent B(1) atoms. There are two shorter (2.08 Å) and two longer (2.15 Å) Ru(1)-B(1) bond lengths. B(1) is bonded in a 7-coordinate geometry to three equivalent Th(1) and four equivalent Ru(1) atoms.
