trans -Bis(acetato-κ O )bis(2-aminoethanol-κ 2 N , O )nickel(II)

In the title compound, [Ni(CH 3 CO 2 ) 2 (C 2 H 7 NO) 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⋯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⋯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.
