Bis(acetato-κO)bis(pyridine-2-aldoxime-κ2 N,N′)nickel(II)

چکیده
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.

In the title mol-ecule, [Cd(CH(3)COO)(2)(C(6)H(6)N(2)O)(2)], the Cd(II) cation is N,N'-chelated by two 2-pyridine-aldoxime ligands and coordinated by two acetate anions in a distorted octa-hedral geometry. The hy-droxy groups of the 2-pyridine-aldoxime ligands link to the acetate anions via intra-molecular O-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯O hydrogen bonds occur in the crystal.
