The material described by NiC2H8(NO2)2(CO)2 is Indium-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four formaldehyde molecules and two NiC2H8(NO2)2 clusters. In each NiC2H8(NO2)2 cluster, Ni(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. C(1) is bonded in a trigonal planar geometry to one N(1), one H(4), and one O(3) atom. N(1) is bonded in a trigonal planar geometry to one C(1), one H(1), and one H(2) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(1) 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 H(3) atom. In the second O site, O(3) is bonded in a bent 120 degrees geometry to one Ni(1) and one C(1) atom. is represented by the CIF card [CIF]
