W2Cu3Ga8 crystallizes in the cubic I-43d space group. W(1) is bonded in a 11-coordinate geometry to three equivalent Cu(1), two equivalent Ga(1), and six equivalent Ga(2) atoms. Cu(1) is bonded in a distorted q6 geometry to two equivalent W(1), two equivalent Ga(1), and six equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 8-coordinate geometry to two equivalent W(1), three equivalent Cu(1), and three equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 5-coordinate geometry to two equivalent W(1), three equivalent Cu(1), and one Ga(1) atom.
W2Cu3Ga8 crystallizes in the cubic I-43d space group. W(1) is bonded in a 11-coordinate geometry to three equivalent Cu(1), two equivalent Ga(1), and six equivalent Ga(2) atoms. All W(1)-Cu(1) bond lengths are 2.73 Å. There is one shorter (2.56 Å) and one longer (2.60 Å) W(1)-Ga(1) bond length. There are three shorter (2.60 Å) and three longer (2.61 Å) W(1)-Ga(2) bond lengths. Cu(1) is bonded in a distorted q6 geometry to two equivalent W(1), two equivalent Ga(1), and six equivalent Ga(2) atoms. Both Cu(1)-Ga(1) bond lengths are 2.60 Å. There are a spread of Cu(1)-Ga(2) bond distances ranging from 2.55-2.68 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 8-coordinate geometry to two equivalent W(1), three equivalent Cu(1), and three equivalent Ga(2) atoms. All Ga(1)-Ga(2) bond lengths are 2.71 Å. In the second Ga site, Ga(2) is bonded in a 5-coordinate geometry to two equivalent W(1), three equivalent Cu(1), and one Ga(1) atom.
