Ta Sb Ru Ru
TaRu2Sb crystallizes in the monoclinic Cm space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded to six Ta(1,1); one Ru(1); and one Ru(2) atom to form a mixture of distorted edge and corner-sharing TaTa6Ru2 hexagonal bipyramids. All Ta(1)-Ta(1,1) bond lengths are 3.10 Å. The Ta(1)-Ru(1) bond length is 3.56 Å. The Ta(1)-Ru(2) bond length is 3.56 Å. In the second Ta site, Ta(1) is bonded to six Ta(1,1); one Ru(1); and one Ru(2) atom to form a mixture of distorted edge and corner-sharing TaTa6Ru2 hexagonal bipyramids. Both Ta(1)-Ta(1) bond lengths are 3.10 Å. The Ta(1)-Ru(1) bond length is 3.56 Å. The Ta(1)-Ru(2) bond length is 3.56 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a single-bond geometry to one Ta(1) and one Sb(1) atom. The Ru(1)-Sb(1) bond length is 0.11 Å. In the second Ru site, Ru(2) is bonded in a single-bond geometry to one Ta(1) and one Sb(1) atom. The Ru(2)-Sb(1) bond length is 1.34 Å. Sb(1) is bonded in a distorted linear geometry to one Ru(1) and one Ru(2) atom.
