The crystal structure described by V2Ni(H2O5)2(H2)2 crystallizes in the monoclinic C2/c space group. The structure consists of eight 1333-74-0 molecules inside a V2Ni(H2O5)2 framework. In the V2Ni(H2O5)2 framework, V(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), and three equivalent O(1) atoms. Ni(1) is bonded in an octahedral geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one O(3) atom. In the second H site, H(3) is bonded in a single-bond geometry to one O(5) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to three equivalent V(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one V(1) and one Ni(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one V(1), one Ni(1), and one H(2) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Ni(1) and one O(5) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one H(3) and one O(4) atom. is represented by the CIF card [CIF]
