La Ta Ru Ru
LaTaRu2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaTaRu2 clusters. La(1) is bonded in a 2-coordinate geometry to two equivalent Ru(1) atoms. Both La(1)-Ru(1) bond lengths are 2.32 Å. Ta(1) is bonded in a 2-coordinate geometry to two equivalent Ru(1) atoms. Both Ta(1)-Ru(1) bond lengths are 2.32 Å. Ru(1) is bonded in a 2-coordinate geometry to one La(1) and one Ta(1) atom.
