UFeGa crystallizes in the hexagonal P-62m space group. U(1) is bonded in a 11-coordinate geometry to one Fe(2), four equivalent Fe(1), and six equivalent Ga(1) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(2) is bonded in a 9-coordinate geometry to three equivalent U(1) and six equivalent Ga(1) atoms. In the second Fe site, Fe(1) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent Ga(1) atoms. Ga(1) is bonded to six equivalent U(1), two equivalent Fe(1), two equivalent Fe(2), and two equivalent Ga(1) atoms to form a mixture of distorted edge, corner, and face-sharing GaU6Ga2Fe4 cuboctahedra.
UFeGa crystallizes in the hexagonal P-62m space group. U(1) is bonded in a 11-coordinate geometry to one Fe(2), four equivalent Fe(1), and six equivalent Ga(1) atoms. The U(1)-Fe(2) bond length is 2.77 Å. All U(1)-Fe(1) bond lengths are 2.79 Å. There are two shorter (2.99 Å) and four longer (3.12 Å) U(1)-Ga(1) bond lengths. There are two inequivalent Fe sites. In the first Fe site, Fe(2) is bonded in a 9-coordinate geometry to three equivalent U(1) and six equivalent Ga(1) atoms. All Fe(2)-Ga(1) bond lengths are 2.53 Å. In the second Fe site, Fe(1) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent Ga(1) atoms. All Fe(1)-Ga(1) bond lengths are 2.56 Å. Ga(1) is bonded to six equivalent U(1), two equivalent Fe(1), two equivalent Fe(2), and two equivalent Ga(1) atoms to form a mixture of distorted edge, corner, and face-sharing GaU6Ga2Fe4 cuboctahedra. Both Ga(1)-Ga(1) bond lengths are 2.71 Å.
