U2Co2Ga crystallizes in the tetragonal P4/mbm space group. U(1) is bonded in a 10-coordinate geometry to six equivalent Co(1) and four equivalent Ga(1) atoms. Co(1) is bonded in a 9-coordinate geometry to six equivalent U(1), one Co(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to eight equivalent U(1) and four equivalent Co(1) atoms to form a mixture of face and corner-sharing GaU8Co4 cuboctahedra.
U2Co2Ga crystallizes in the tetragonal P4/mbm space group. U(1) is bonded in a 10-coordinate geometry to six equivalent Co(1) and four equivalent Ga(1) atoms. There are two shorter (2.57 Å) and four longer (2.77 Å) U(1)-Co(1) bond lengths. All U(1)-Ga(1) bond lengths are 3.12 Å. Co(1) is bonded in a 9-coordinate geometry to six equivalent U(1), one Co(1), and two equivalent Ga(1) atoms. The Co(1)-Co(1) bond length is 2.68 Å. Both Co(1)-Ga(1) bond lengths are 2.78 Å. Ga(1) is bonded to eight equivalent U(1) and four equivalent Co(1) atoms to form a mixture of face and corner-sharing GaU8Co4 cuboctahedra.
