NiC5PO2 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two NiC5PO2 clusters. Ni(1) is bonded in a distorted trigonal planar geometry to one C(1), one O(1), and one O(2) atom. There are five inequivalent C sites. In the first C site, C(1) is bonded in a bent 150 degrees geometry to one Ni(1) and one P(1) atom. In the second C site, C(2) is bonded in a 2-coordinate geometry to one C(3) and one P(1) atom. In the third C site, C(3) is bonded in a 3-coordinate geometry to one C(2), one C(4), and one P(1) atom. In the fourth C site, C(4) is bonded in a 2-coordinate geometry to one C(3) and one P(1) atom. In the fifth C site, C(5) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. P(1) is bonded in a 4-coordinate geometry to one C(1), one C(2), one C(3), and one C(4) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a water-like geometry to one Ni(1) and one C(5) atom. In the second O site, O(1) is bonded in a water-like geometry to one Ni(1) and one C(5) atom.
