PtIn2Ga crystallizes in the trigonal R3m space group. Pt(1) is bonded in a 11-coordinate geometry to three equivalent In(2), four equivalent In(1), and four equivalent Ga(1) atoms. All Pt(1)-In(2) bond lengths are 3.18 Å. There are three shorter (2.91 Å) and one longer (3.26 Å) Pt(1)-In(1) bond length. There are three shorter (2.91 Å) and one longer (3.26 Å) Pt(1)-Ga(1) bond length. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 11-coordinate geometry to four equivalent Pt(1), four equivalent In(2), and three equivalent Ga(1) atoms. There are three shorter (2.91 Å) and one longer (3.26 Å) In(1)-In(2) bond length. All In(1)-Ga(1) bond lengths are 3.18 Å. In the second In site, In(2) is bonded in a distorted single-bond geometry to three equivalent Pt(1), four equivalent In(1), and one Ga(1) atom. The In(2)-Ga(1) bond length is 2.19 Å. Ga(1) is bonded in a 4-coordinate geometry to four equivalent Pt(1), one In(2), and three equivalent In(1) atoms.
