Sm(RuB)2 crystallizes in the orthorhombic Fddd space group. Sm(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 Sm(1) and four equivalent B(1) atoms. B(1) is bonded in a 7-coordinate geometry to three equivalent Sm(1) and four equivalent Ru(1) atoms.
Sm(RuB)2 crystallizes in the orthorhombic Fddd space group. Sm(1) is bonded in a 10-coordinate geometry to four equivalent Ru(1) and six equivalent B(1) atoms. All Sm(1)-Ru(1) bond lengths are 3.00 Å. There are two shorter (2.84 Å) and four longer (3.02 Å) Sm(1)-B(1) bond lengths. Ru(1) is bonded in a 4-coordinate geometry to two equivalent Sm(1) and four equivalent B(1) atoms. There are two shorter (2.06 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 Sm(1) and four equivalent Ru(1) atoms.
