The crystal structure described by Ca2Cu2Ga crystallizes in the orthorhombic Immm space group. Ca(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent Ga(1) atoms. Cu(1) is bonded in a 10-coordinate geometry to six equivalent Ca(1), two equivalent Cu(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to eight equivalent Ca(1) and four equivalent Cu(1) atoms to form a mixture of distorted edge and face-sharing GaCa8Cu4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
