Bis(2-aminopyridine-N)bis(benzoato-O)zinc

The crystal structure of the title compound, [Zn(C7H5O2)(2) (C5H6N2)(2)], i s built of monomeric [Zn(2-apy)(2) (OBz)(2)] molecules (apy is aminopyridin e and OBz is benzoate). The Zn atom lies on a twofold symmetry axis and ado pts a slightly distorted tetrahedral coordination. The Zn ... O distances t o the non-coordinated O atoms are long at 2.872 (3) Angstrom. Each non-liga ting carbonyl O atom of the benzoate anion accepts one intramolecular and o ne intermolecular hydrogen bond from the amino group. The molecules form a chain along the c axis through intermolecular N-H ... O hydrogen bonds betw een the amino and carboxyl groups.
