The material structure described by Ca3Ir2Ga3 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 10-coordinate geometry to three equivalent Ir(1), two equivalent Ga(1), and five equivalent Ga(2) atoms. In the second Ca site, Ca(2) is bonded in a 9-coordinate geometry to four equivalent Ir(1), two equivalent Ga(2), and three equivalent Ga(1) atoms. Ir(1) is bonded in a 4-coordinate geometry to two equivalent Ca(2), three equivalent Ca(1), one Ga(1), and three equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to three equivalent Ca(2), four equivalent Ca(1), and two equivalent Ir(1) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to one Ca(2), five equivalent Ca(1), and three equivalent Ir(1) atoms. is represented by the CIF file [CIF]
