Ga3Pt2 crystallizes in the trigonal P-3m1 space group. Pt(1) is bonded in a body-centered cubic geometry to three equivalent Ga(1) and five equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 6-coordinate geometry to six equivalent Pt(1) atoms. In the second Ga site, Ga(2) is bonded in a 5-coordinate geometry to five equivalent Pt(1) atoms.
