The structure described by (Ni6C4O15)4O2 crystallizes in the cubic P-43m space group. The structure consists of one water atom inside a Ni6C4O15 framework. In the Ni6C4O15 framework, Ni(1) is bonded to one O(3), one O(4), two equivalent O(2), and two equivalent O(5) atoms to form a mixture of edge and corner-sharing NiO6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to three equivalent O(2) atoms. In the second C site, C(2) is bonded in a trigonal planar geometry to three equivalent O(5) atoms. There are four inequivalent O sites. In the first O site, O(3) is bonded in a square co-planar geometry to four equivalent Ni(1) atoms. In the second O site, O(4) is bonded in a square co-planar geometry to four equivalent Ni(1) atoms. In the third O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Ni(1) and one C(2) atom. In the fourth O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Ni(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
