The crystal structure described by UCuGa crystallizes in the hexagonal P6_3/mmc space group. U(1) is bonded in a 14-coordinate geometry to two equivalent U(1), six equivalent Cu(1), and six equivalent Ga(1) atoms. Cu(1) is bonded in a distorted q6 geometry to six equivalent U(1) and five equivalent Ga(1) atoms. Ga(1) is bonded in a 11-coordinate geometry to six equivalent U(1) and five equivalent Cu(1) atoms. is represented by the CIF card [CIF]
