Hexaaqua-zinc(II) bis-[4-(2-hydroxy-benzyl-ideneamino)benzene-sulfonate].

In the title compound, [Zn(H2O)6](C13H10NO4S)2, a distorted ZnO6 octahedron results from the coordination by the six water molecules. Only three of the water molecules are crystallographically unique, as the Zn atom lies on an inversion center. The Zn—O bond lengths are in the range 2.054 (4)–2.073 (4) Å. A network of hydrogen bonds helps to establish the crystal packing.

Bis(4‐methoxybenzaldehyde 2‐hydroxybenzoylhydrazonato)pyridinezinc(II) pyridine solvate

In the title compound, [Zn(C15H13N2O3)2(C5H5N)] C5H5N, a distorted ZnN3O2 trigonal–bipyramidal coordination geometry results from the coordination of the two bidentate ligands and one pyridine molecule. A crystallographic twofold rotation axis passes through Zn and the pyridine ligand. The pyridine solvent molecule is disordered over an inversion centre. Intermolecular C—H O and intramolecular C— H O and O—H N hydrogen-bonding interactions help to establish the crystal packing.

2-Hydr­oxy-N-(2-phenoxy­ethyl)benzamide

The crystal structure of the title compound, C15H15NO3, is stabilized by weak O—H⋯O and N—H⋯O hydrogen bonds. The dihedral angle between the two benzene rings is 70.4 (2)°.

3,4-Dimethylbenzaldehyde (3-pyridylcarbonyl)hydrazone monohydrate

In the crystal structure of the title compound, C15H15N3O·H2O, O—H⋯O, O—H⋯N, N—H⋯O and C—H⋯O hydrogen bonds occur.
