The tridentate Schiff base ligand 2,4-dihydroxyacetophenone salicylhydrazide, derived from the condensation of 2,4-dihydroxyacetophenone and salicylhydrazide, in the presence of pyridine and N,N′-dimethylformamide, forms a dinuclear distorted square-pyramidal Zn complex with Zn(OAc)2·2H2O, viz. [Zn2(C15H12N2O4)2(C5H5N)2]·2C3H7NO. The complex is centrosymmetric and the two Zn atoms are bridged by two phenolate O atoms.

In the title complex, [Ni(C2H8N2)2(H2O)2](C10H8NO3S)2·2H2O, the Ni atom of the centrosymmetric cation has a distorted octahedral coordination geometry, and is bonded to four N atoms, from two diethylenediamine ligands, and to two water O atoms. Symmetry-related 4-aminonaphthalene-1-sulfonate anions are antiparallel. The crystal structure is stabilized by π–π interactions and N—H
O, O—HO and O—HN hydrogen bonds.

In the title compound, [Cu(C2H8N2)2(H2O)2](C10H8NO3S)2·2H2O, the CuII complex cation, located on an inversion centre, has a distorted octahedral coordination geometry formed by two ethylenediamine and two water molecules. The distance of 3.4987 (11) Å between the centroids of neighbouring parallel aromatic rings of aminonaphthalenesulfonate anions suggests the existence of π–π stacking.
