The compound described by Pt3Ga crystallizes in the tetragonal P4/mbm space group. There are three inequivalent Pt sites. In the first Pt site, Pt(3) is bonded in a 10-coordinate geometry to two equivalent Pt(3), four equivalent Pt(1), and four equivalent Pt(2) atoms. In the second Pt site, Pt(1) is bonded in a 4-coordinate geometry to four equivalent Pt(3) and four equivalent Ga(1) atoms. In the third Pt site, Pt(2) is bonded in a 2-coordinate geometry to four equivalent Pt(3) and four equivalent Ga(1) atoms. Ga(1) is bonded in a 8-coordinate geometry to four equivalent Pt(1) and four equivalent Pt(2) atoms. is represented by the CIF card [CIF]
