Ni(HO)4(C2O)2(H2O)4 is Indium-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two 1,3-butadiyne-1,4-diol molecules; eight water molecules; and two Ni(HO)4 clusters. In each Ni(HO)4 cluster, Ni(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(3) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(3) atom. In the second H site, H(6) is bonded in a single-bond geometry to one O(3) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Ni(1) atom. In the second O site, O(3) is bonded in a distorted water-like geometry to one Ni(1), one H(1), and one H(6) atom.
