PtNi3Ga4 crystallizes in the trigonal R3 space group. Pt(1) is bonded in a 13-coordinate geometry to six equivalent Ni(1), one Ga(1), and six equivalent Ga(2) atoms. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Pt(1), two 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 7-coordinate geometry to one Pt(1) and six equivalent Ni(1) atoms. In the second Ga site, Ga(2) is bonded in a 7-coordinate geometry to two equivalent Pt(1) and five equivalent Ni(1) atoms.
PtNi3Ga4 crystallizes in the trigonal R3 space group. Pt(1) is bonded in a 13-coordinate geometry to six equivalent Ni(1), one Ga(1), and six equivalent Ga(2) atoms. There are three shorter (2.91 Å) and three longer (2.93 Å) Pt(1)-Ni(1) bond lengths. The Pt(1)-Ga(1) bond length is 2.52 Å. There are three shorter (2.52 Å) and three longer (2.67 Å) Pt(1)-Ga(2) bond lengths.
