RuCdGeCd is alpha carbon monoxide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two cadmium;germanium molecules and two RuCd clusters. In each RuCd cluster, Ru(1) is bonded in a single-bond geometry to one Cd(2) atom. The Ru(1)-Cd(2) bond length is 1.00 Å. Cd(2) is bonded in a single-bond geometry to one Ru(1) atom.
