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.

In the centrosymmetric title compound, [Cu(C5H11N2O2)2], the Cu2+ ion, located on an inversion centre (Wyckoff position 2b), is in a square-planar environment, surounded by four O atoms of the N—O groups of two N-nitroso-N-pentylhydroxylaminate ligands [Cu—O = 1.9042 (17) and 1.9095 (16) Å]. The hydroxylaminate monoanions are bidentate chelating ligands. The Cu2+ cations form stacks along [010], with intermolecular CuN contacts of 3.146 (2) and 3.653 (2) Å.
