The compound described by CaNiGe2 crystallizes in the orthorhombic Cmcm space group. Ca(1) is bonded in a 14-coordinate geometry to four equivalent Ni(1), four equivalent Ge(1), and six equivalent Ge(2) atoms. Ni(1) is bonded in a 9-coordinate geometry to four equivalent Ca(1), one Ge(2), and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to four equivalent Ca(1) and four equivalent Ni(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to six equivalent Ca(1), one Ni(1), and two equivalent Ge(2) atoms. is represented by the CIF file [CIF]
