Cr Ga Ge
CrGaGe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrGaGe clusters. Cr(1) is bonded in a single-bond geometry to one Ga(1) atom. The Cr(1)-Ga(1) bond length is 0.86 Å. Ga(1) is bonded in a distorted single-bond geometry to one Cr(1) and one Ge(1) atom. The Ga(1)-Ge(1) bond length is 2.06 Å. Ge(1) is bonded in a single-bond geometry to one Ga(1) atom.
