In the mononuclear title compound, [Ni(CH3COO)2(C6H6N2O)2], the NiII atom is coordinated by two pyridine-2-aldoxime (PaoH) ligands and two acetate groups, with cis coordination for the pairs of identical ligands. While each acetate group binds to the NiII atom by one O atom, each PaoH chelates the NiII atom through two N atoms. The O atom on PaoH is not deprotonated and does not participate in bonding to the NiII atom. Thus, the NiII atom exhibits an octa­hedral environment. Intra­molecular O—H⋯O hydrogen-bonding inter­actions and inter­molecular C—H⋯O hydrogen-bonding inter­actions are present in the structure. Adjacent mol­ecules pack along [100] through van der Waals forces.
