Ba(CuP2)2 crystallizes in the orthorhombic Fddd space group. Ba(1) is bonded in a 12-coordinate geometry to four equivalent Cu(1) and eight equivalent P(1) atoms. Cu(1) is bonded to two equivalent Ba(1) and four equivalent P(1) atoms to form a mixture of distorted corner and edge-sharing CuBa2P4 tetrahedra. P(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Cu(1), and two equivalent P(1) atoms.
Ba(CuP2)2 crystallizes in the orthorhombic Fddd space group. Ba(1) is bonded in a 12-coordinate geometry to four equivalent Cu(1) and eight equivalent P(1) atoms. All Ba(1)-Cu(1) bond lengths are 3.57 Å. There are four shorter (3.22 Å) and four longer (3.35 Å) Ba(1)-P(1) bond lengths. Cu(1) is bonded to two equivalent Ba(1) and four equivalent P(1) atoms to form a mixture of distorted corner and edge-sharing CuBa2P4 tetrahedra. There are two shorter (2.30 Å) and two longer (2.36 Å) Cu(1)-P(1) bond lengths. P(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Cu(1), and two equivalent P(1) atoms. There is one shorter (2.18 Å) and one longer (2.34 Å) P(1)-P(1) bond length.
