In the title compound, [Ni(C2H3O)(2)(C3H4N2)(4)], the Ni atom is coordinate
d centrosymmetrically by four N and two O atoms in an octahedral coordinati
on [Ni-N = 1.986 (3) and 2.054 (3) Angstrom; Ni-O = 2.697 (3) Angstrom]. Th
e O atoms of the acetate anions form hydrogen bonds to adjacent imidazole m
oieties, with the free O atom forming a somewhat shorter bond [N ... O = 2.
679 (3) and 2.870 (4) Angstrom]. The hydrogen bonds give rise to a two-dime
nsional layer structure.
