WGaSe crystallizes in the triclinic P1 space group. W(1) is bonded in a 4-coordinate geometry to two equivalent Ga(1) and two equivalent Se(1) atoms. There is one shorter (2.08 Å) and one longer (2.37 Å) W(1)-Ga(1) bond length. There is one shorter (2.31 Å) and one longer (2.87 Å) W(1)-Se(1) bond length. Ga(1) is bonded in a 4-coordinate geometry to two equivalent W(1) and two equivalent Se(1) atoms. There is one shorter (1.79 Å) and one longer (2.13 Å) Ga(1)-Se(1) bond length. Se(1) is bonded in a 2-coordinate geometry to two equivalent W(1) and two equivalent Ga(1) atoms.
