In the centrosymmetric title compound, [Ni(C7H6FN2O2)2(H2O)2], the NiII 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.

We describe the thermal decomposition of a number of copper(II) alkyl and benzylnitrosohy droxylaminates via thermostating in polyethylene glycol and 2 dodecyl 1H imidazole for various lengths of time. This process is shown to lead to the formation of copper(I) oxide nanoparticles, which have been char acterized by X ray diffraction and electron spectroscopy. The starting copper(II) nitrosohydroxylaminates have been characterized by thermogravimetry.
