Ba(CuP)2 crystallizes in the orthorhombic Fddd space group. Ba(1) is bonded to six equivalent Cu(1) and two equivalent P(1) atoms to form edge-sharing BaCu6P2 hexagonal bipyramids. Cu(1) is bonded in a distorted single-bond geometry to three equivalent Ba(1), one Cu(1), and one P(1) atom. P(1) is bonded in a 4-coordinate geometry to one Ba(1), one Cu(1), and two equivalent P(1) atoms.
Ba(CuP)2 crystallizes in the orthorhombic Fddd space group. Ba(1) is bonded to six equivalent Cu(1) and two equivalent P(1) atoms to form edge-sharing BaCu6P2 hexagonal bipyramids. There are a spread of Ba(1)-Cu(1) bond distances ranging from 3.25-3.77 Å. Both Ba(1)-P(1) bond lengths are 3.12 Å. Cu(1) is bonded in a distorted single-bond geometry to three equivalent Ba(1), one Cu(1), and one P(1) atom. The Cu(1)-Cu(1) bond length is 2.30 Å. The Cu(1)-P(1) bond length is 2.28 Å. P(1) is bonded in a 4-coordinate geometry to one Ba(1), one Cu(1), and two equivalent P(1) atoms. There is one shorter (2.20 Å) and one longer (2.21 Å) P(1)-P(1) bond length.
