Co Mo Ru Ru
MoRu2Co is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MoRu2Co clusters. Mo(1) is bonded in a 2-coordinate geometry to two equivalent Ru(1) atoms. Both Mo(1)-Ru(1) bond lengths are 0.95 Å. Ru(1) is bonded in a 2-coordinate geometry to one Mo(1), one Ru(1), and one Co(1) atom. The Ru(1)-Ru(1) bond length is 0.47 Å. The Ru(1)-Co(1) bond length is 0.49 Å. Co(1) is bonded in a 2-coordinate geometry to two equivalent Ru(1) atoms.
