Ga As As W
WGaAs2 crystallizes in the triclinic P1 space group. W(1) is bonded in a 1-coordinate geometry to one Ga(1) and two equivalent As(2) atoms. The W(1)-Ga(1) bond length is 2.20 Å. There is one shorter (2.62 Å) and one longer (3.20 Å) W(1)-As(2) bond length. Ga(1) is bonded in a 2-coordinate geometry to one W(1), one As(1), and one As(2) atom. The Ga(1)-As(1) bond length is 2.21 Å. The Ga(1)-As(2) bond length is 2.75 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 1-coordinate geometry to one Ga(1) and one As(2) atom. The As(1)-As(2) bond length is 2.54 Å. In the second As site, As(2) is bonded in a 6-coordinate geometry to two equivalent W(1), one Ga(1), one As(1), and two equivalent As(2) atoms. Both As(2)-As(2) bond lengths are 2.78 Å.
