Ni(C2O)2(CO)2O2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight formaldehyde molecules, four hydrogen peroxide molecules, and four Ni(C2O)2 clusters. In each Ni(C2O)2 cluster, Ni(1) is bonded in a linear geometry to two equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one O(2) atom. In the second C site, C(2) is bonded in a bent 150 degrees geometry to one Ni(1) and one C(3) atom. O(2) is bonded in a single-bond geometry to one C(3) atom.

The structure is zero-dimensional and consists of eight formaldehyde molecules, four hydrogen peroxide molecules, and four Ni(C2O)2 clusters. In each Ni(C2O)2 cluster, Ni(1) is bonded in a linear geometry to two equivalent C(2) atoms. Both Ni(1)-C(2) bond lengths are 1.84 Å. There are two inequivalent C sites. In the first C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one O(2) atom. The C(3)-C(2) bond length is 1.30 Å. The C(3)-O(2) bond length is 1.19 Å. In the second C site, C(2) is bonded in a bent 150 degrees geometry to one Ni(1) and one C(3) atom. O(2) is bonded in a single-bond geometry to one C(3) atom.
