Catena-Poly[[[aqua-bis-(4,4'-bipyridine-κN)zinc]-μ-l-tyrosinato-κN,O:O] nitrate dihydrate].

ABSTRACT: In the title compound, {[Zn(C(9)H(10)NO(3))(C(10)H(8)N(2))(2)(H(2)O)]NO(3)·2H(2)O}(n), the Zn(II) atom is six-coordinated in a distorted octa-hedral geometry by two carboxyl-ate O atoms and one amino N atom from two l-tyrosinate ligands, two N atoms from two 4,4'-bipyridine ligands, and one water mol-ecule. Adjacent Zn atoms are bridged by the bidentate carboxyl-ate groups into a cationic chain extending along [010]. N-H⋯N, O-H⋯N and O-H⋯O hydrogen bonds link the cationic chains, nitrate anions and uncoordinated water mol-ecules into a supra-molecular network. π-π inter-actions between the pyridine rings and between the pyridine and benzene rings [centroid-centroid distances = 3.615 (4) and 3.636 (4) Å] are present.
