The compound described by U(Cr3P2)2 crystallizes in the orthorhombic Pmmn space group. U(1) is bonded to two equivalent Cr(3), four equivalent Cr(1), two equivalent P(3), and four equivalent P(2) atoms to form distorted UCr6P6 cuboctahedra that share corners with four equivalent Cr(1)U2P4 tetrahedra, edges with two equivalent Cr(3)U2P4 tetrahedra, edges with six equivalent Cr(1)U2P4 tetrahedra, and faces with two equivalent U(1)Cr6P6 cuboctahedra. There are four inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to two equivalent U(1), one P(2), and three equivalent P(3) atoms to form distorted CrU2P4 tetrahedra that share corners with two equivalent U(1)Cr6P6 cuboctahedra, corners with two equivalent Cr(3)U2P4 tetrahedra, corners with eight equivalent Cr(1)U2P4 tetrahedra, edges with three equivalent U(1)Cr6P6 cuboctahedra, edges with five equivalent Cr(1)U2P4 tetrahedra,  a faceface with one Cr(1)U2P4 tetrahedra, and  a faceface with one Cr(3)U2P4 tetrahedra. In the second Cr site, Cr(2) is bonded in a 5-coordinate geometry to two equivalent P(2) and three equivalent P(1) atoms. In the third Cr site, Cr(3) is bonded to two equivalent U(1), two equivalent P(1), and two equivalent P(2) atoms to form distorted CrU2P4 tetrahedra that share corners with four equivalent Cr(1)U2P4 tetrahedra, edges with two equivalent U(1)Cr6P6 cuboctahedra, edges with two equivalent Cr(3)U2P4 tetrahedra, and faces with two equivalent Cr(1)U2P4 tetrahedra. In the fourth Cr site, Cr(4) is bonded in a 5-coordinate geometry to one P(3) and four equivalent P(2) atoms. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 8-coordinate geometry to two equivalent Cr(3) and six equivalent Cr(2) atoms. In the second P site, P(2) is bonded in a 8-coordinate geometry to two equivalent U(1), one Cr(1), one Cr(3), two equivalent Cr(2), and two equivalent Cr(4) atoms.
