The structure described by UYGa4 is hexagonal omega structure-derived structured and crystallizes in the orthorhombic Pmmm space group. U(1) is bonded to four equivalent Ga(1) and eight equivalent Ga(2) atoms to form UGa12 cuboctahedra that share edges with four equivalent U(1)Ga12 cuboctahedra, edges with eight equivalent Y(1)Ga12 cuboctahedra, faces with four equivalent U(1)Ga12 cuboctahedra, and faces with four equivalent Y(1)Ga12 cuboctahedra. Y(1) is bonded to four equivalent Ga(2) and eight equivalent Ga(1) atoms to form YGa12 cuboctahedra that share edges with four equivalent Y(1)Ga12 cuboctahedra, edges with eight equivalent U(1)Ga12 cuboctahedra, faces with four equivalent U(1)Ga12 cuboctahedra, and faces with four equivalent Y(1)Ga12 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to two equivalent U(1), four equivalent Y(1), one Ga(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to four equivalent U(1), two equivalent Y(1), one Ga(2), and two equivalent Ga(1) atoms. is represented by the CIF card [CIF]
