Bis(acetato-?O)bis-(pyridine-2-aldoxime-?(2)N,N')nickel(II).

ABSTRACT: In the mononuclear title compound, [Ni(CH(3)COO)(2)(C(6)H(6)N(2)O)(2)], the Ni(II) 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 Ni(II) atom by one O atom, each PaoH chelates the Ni(II) atom through two N atoms. The O atom on PaoH is not deprotonated and does not participate in bonding to the Ni(II) atom. Thus, the Ni(II) atom exhibits an octa-hedral environment. Intra-molecular O-H?O hydrogen-bonding inter-actions and inter-molecular C-H?O hydrogen-bonding inter-actions are present in the structure. Adjacent mol-ecules pack along [100] through van der Waals forces.
