The material structure described by UCoGa crystallizes in the hexagonal P-62m space group. U(1) is bonded in a 11-coordinate geometry to one Co(2), four equivalent Co(1), and six equivalent Ga(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(2) is bonded in a distorted q6 geometry to three equivalent U(1) and six equivalent Ga(1) atoms. In the second Co site, Co(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 Co(1), two equivalent Co(2), and two equivalent Ga(1) atoms to form a mixture of distorted edge, corner, and face-sharing GaU6Ga2Co4 cuboctahedra. is represented by the CIF file [CIF]
