چکیده
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.

The title compound, {(C(10)H(10)N(2))[Cd(SO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)]·2H(2)O}(n), consists of anionic chains of the Cd complex, diprotonated 4,4'-bipyridinium cations and uncoordinated water mol-ecules. In the anionic chain, the Cd atom lies on a center of inversion in an octa-hedral geometry. The midpoint of the coordinated bipyridine also resides on a center of inversion, as does the n...

The reaction of 2-hy-droxy-1,4-naphtho-quinone and 4,4'-bipyridine with zinc acetate produced the title compound, [Zn(C(10)H(5)O(3))(2)(C(10)H(8)N(2))(H(2)O)]·C(10)H(8)N(2)·2H(2)O. The bond lengths and angles around the metal atom indicate a deviation from octa-hedral geometry. The two naphtho-quinone ligands coordinate in a cis fashion, with the 4,4'-bipyridine ligand and the water mol-ecules ...
