PtCu4Ga crystallizes in the trigonal R3m space group. Pt(1) is bonded in a 3-coordinate geometry to three equivalent Cu(1), three equivalent Cu(2), and three equivalent Ga(1) atoms. All Pt(1)-Cu(1) bond lengths are 2.22 Å. All Pt(1)-Cu(2) bond lengths are 3.07 Å. All Pt(1)-Ga(1) bond lengths are 2.82 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 3-coordinate geometry to one Pt(1), two equivalent Cu(1), three equivalent Cu(2), and three equivalent Ga(1) atoms. Both Cu(1)-Cu(1) bond lengths are 1.42 Å. There is one shorter (2.47 Å) and two longer (2.96 Å) Cu(1)-Cu(2) bond lengths. There are two shorter (2.89 Å) and one longer (3.14 Å) Cu(1)-Ga(1) bond length. In the second Cu site, Cu(2) is bonded in a 16-coordinate geometry to three equivalent Pt(1), nine equivalent Cu(1), and four equivalent Ga(1) atoms. There are three shorter (2.91 Å) and one longer (3.10 Å) Cu(2)-Ga(1) bond length. Ga(1) is bonded in a 16-coordinate geometry to three equivalent Pt(1), four equivalent Cu(2), and nine equivalent Cu(1) atoms.
