The material described by U(Ga) crystallizes in the orthorhombic Cmcm space group. There are three inequivalent U sites. In the first U site, U(1) is bonded to two equivalent U(2), two equivalent U(3), and four equivalent Ga(1) atoms to form a mixture of corner and edge-sharing UU4Ga4 hexagonal bipyramids. In the second U site, U(2) is bonded in a distorted q6 geometry to two equivalent U(1), four equivalent Ga(1), and four equivalent Ga(2) atoms. In the third U site, U(3) is bonded in a 9-coordinate geometry to one U(1), two equivalent U(3), two equivalent Ga(1), and four equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 8-coordinate geometry to two equivalent U(1), two equivalent U(2), two equivalent U(3), and two equivalent Ga(1) atoms. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to two equivalent U(2), four equivalent U(3), and two equivalent Ga(2) atoms. is represented by the CIF card [CIF]
