Bis(μ(2)-pyridine-2-carboxamide oximato)bis-[(pyridine-2-carboxamide oxime)zinc] dinitrate.

In the title dinuclear compound, Zn(2)(C(6)H(6)N(3)O)(2)(C(6)H(7)N(3)O)(2)(2), the Zn(II) cation is N,N'-chelated by one pyridine-2-carboxamide oximate anion and one pyridine-2-carboxamide oxime mol-ecule, and is further bridged by an oxime O atom from the adjacent pyridine-2-carboxamide oximate anion, forming a distorted trigonal bipyramidal coordination. Two pyridine-2-carboxamide oximate anions bridge two Zn(II) cations to form the centrosymmetric dinuclear mol-ecule. Extensive O-H⋯O, N-H⋯O and O-H⋯N hydrogen bonds are present in the crystal structure.
