Cu2P2(CO2)3 crystallizes in the orthorhombic Pnc2 space group. Cu(1) is bonded in a distorted see-saw-like geometry to one O(1), one O(3), and two equivalent O(2) atoms. The Cu(1)-O(1) bond length is 1.86 Å. The Cu(1)-O(3) bond length is 1.93 Å. There is one shorter (1.96 Å) and one longer (2.17 Å) Cu(1)-O(2) bond length. There are two inequivalent C sites. In the first C site, C(1) is bonded in a bent 120 degrees geometry to one C(2) and one P(1) atom. The C(1)-C(2) bond length is 1.47 Å. The C(1)-P(1) bond length is 1.86 Å. In the second C site, C(2) is bonded in a bent 120 degrees geometry to two equivalent C(1) atoms. P(1) is bonded in a distorted tetrahedral geometry to one C(1), one O(1), one O(2), and one O(3) atom. The P(1)-O(1) bond length is 1.53 Å. The P(1)-O(2) bond length is 1.62 Å. The P(1)-O(3) bond length is 1.49 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Cu(1) and one P(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Cu(1) and one P(1) atom. Linkers: 2 [O]P([O])(=O)[C][C][C]P([O])([O])=O. Metal clusters: 4 [Cu].
