The structure described by UPr2P3 is Caswellsilverite-like structured and crystallizes in the orthorhombic Immm space group. U(1) is bonded to two equivalent P(1) and four equivalent P(2) atoms to form UP6 octahedra that share corners with two equivalent U(1)P6 octahedra, corners with four equivalent Pr(1)P6 octahedra, edges with two equivalent U(1)P6 octahedra, and edges with ten equivalent Pr(1)P6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. Pr(1) is bonded to two equivalent P(1) and four equivalent P(2) atoms to form PrP6 octahedra that share corners with two equivalent U(1)P6 octahedra, corners with four equivalent Pr(1)P6 octahedra, edges with five equivalent U(1)P6 octahedra, and edges with seven equivalent Pr(1)P6 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent U(1) and four equivalent Pr(1) atoms to form a mixture of corner and edge-sharing PPr4U2 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. In the second P site, P(2) is bonded to two equivalent U(1) and four equivalent Pr(1) atoms to form a mixture of corner and edge-sharing PPr4U2 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. is represented by the CIF file [CIF]
