The material described by Ca3(PtGa)2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 9-coordinate geometry to four equivalent Pt(1), two equivalent Ga(2), and three equivalent Ga(1) atoms. In the second Ca site, Ca(2) is bonded in a 7-coordinate geometry to four equivalent Pt(1) and three equivalent Ga(2) atoms. Pt(1) is bonded in a 9-coordinate geometry to two equivalent Ca(2), four equivalent Ca(1), one Ga(2), and two equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to six equivalent Ca(1) and four equivalent Pt(1) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to three equivalent Ca(2), four equivalent Ca(1), and two equivalent Pt(1) atoms. is represented by the CIF file [CIF]
