Co Si Ru Ru
(Ru)2CoSi is High Pressure Cadmuum Telluride structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two cobalt monosilicide molecules and two Ru clusters. In each Ru cluster, there are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a distorted single-bond geometry to one Ru(2) atom. The Ru(1)-Ru(2) bond length is 1.40 Å. In the second Ru site, Ru(2) is bonded in a distorted single-bond geometry to one Ru(1) atom.
