Ba Ba Sb Ru
Ba2RuSb crystallizes in the monoclinic Cm space group. Ba(1) is bonded in a 4-coordinate geometry to four equivalent Ru(1) and two equivalent Sb(1) atoms. There are a spread of Ba(1)-Ru(1) bond distances ranging from 2.89-4.10 Å. There is one shorter (2.89 Å) and one longer (3.31 Å) Ba(1)-Sb(1) bond length. Ru(1) is bonded in a 9-coordinate geometry to eight equivalent Ba(1) and one Sb(1) atom. The Ru(1)-Sb(1) bond length is 3.24 Å. Sb(1) is bonded in a 4-coordinate geometry to four equivalent Ba(1) and one Ru(1) atom.
