trans-Bis(acetato-kappa O)bis(2-amino-ethanol-kappa N-2, O) nickel(II)

In the title compound, [Ni(CH3CO2)(2)(C2H7NO)(2)], the Ni II cation, located on an inversion center, is N, O-chelated by two 2-aminoethanol molecules and further coordinated by two monodendate acetate anions in a slightly distorted octahedral geometry. The latter is stabilized by intramolecular O-H center dot center dot center dot O hydrogen bonds involving the non-coordinated O atom of the acetate and the H atom of the hydroxy group of the 2-aminoethanol ligand. In the crystal, N-H center dot center dot center dot O hydrogen bonds link the molecules into a three-dimensional supramolecular framework that involves (a) the coordinated acetate O atom and one of the H atoms of the amino group and (b) the non-coordinated acetate O atom and the other H atom of the amino group.
