The crystal structure described by UPd2Cu3 crystallizes in the orthorhombic Imm2 space group. U(1) is bonded in a 16-coordinate geometry to six equivalent Pd(1), four equivalent Cu(2), and six equivalent Cu(1) atoms. Pd(1) is bonded to three equivalent U(1), two equivalent Pd(1), three equivalent Cu(2), and four equivalent Cu(1) atoms to form a mixture of distorted corner, edge, and face-sharing PdU3Cu7Pd2 cuboctahedra. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 12-coordinate geometry to three equivalent U(1), four equivalent Pd(1), two equivalent Cu(1), and three equivalent Cu(2) atoms. In the second Cu site, Cu(2) is bonded in a 16-coordinate geometry to four equivalent U(1), six equivalent Pd(1), and six equivalent Cu(1) atoms. is represented by the CIF file [CIF]
