Di­aqua­bis­[N-(2-fluoro­benz­yl)-N-nitroso­hydroxy­laminato-κ²O,O′]nickel(II)

In the centrosymmetric title compound, [Ni(C₇H₆FN₂O₂)₂(H₂O)₂], the Ni^II cation is in a slightly distorted octa­hedral environment and is surrounded by four O atoms from the N—O groups of the organic ligands [Ni—O = 2.0179 (13) and 2.0283 (12) Å], and two water mol­ecules [Ni—O = 2.0967 (14) Å]. The N-(2-fluoro­benz­yl)-N-nitroso­hydroxy­laminate monoanions act as bidentate chelating ligands. In the crystal, the Ni cations in the columns are shifted in such a way that the coordinated water mol­ecules are involved in the formation of hydrogen bonds with the O atoms of the organic species of neighbouring mol­ecules. Thus, a two-dimensional network parallel to (100) is built up by hydrogen-bonded molecules.
