【 摘 要 】
In the title compound, [Zn(C4H8NOS2)2(C12H10N4)], the ZnII atom exists within a NS4 donor set defined by two chelating dithiocarbamate ligands and a pyridyl-N atom derived from a terminally bound 4-pyridinealdazine ligand. The distorted coordination geometry tends towards square-pyramidal with the pyridyl-N atom occupying the apical position. In the crystal, hydroxyl-O—H⋯O(hydroxyl) and hydroxyl-O—H⋯N(pyridyl) hydrogen-bonding give rise to a supramolecular double-chain along [1-10]; methyl-C—H⋯π(chelate ring) interactions help to consolidate the chain. The chains are connected into a three-dimensional architecture via pyridyl-C—H⋯O(hydroxyl) interactions. In addition to the contacts mentioned above, the Hirshfeld surface analysis points to the significance of relatively weak π–π interactions between pyridyl rings [inter-centroid distance = 3.901 (3) Å].
