The material structure described by CaGe2 crystallizes in the monoclinic C2/m space group. Ca(1) is bonded to twelve equivalent Ge(1) atoms to form a mixture of distorted edge and face-sharing CaGe12 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Ca(1) and three equivalent Ge(1) atoms. is represented by the CIF file [CIF]
