Bis[N-2-hy­droxy­ethyl,N-methyl­dithio­carbamato-κ2S,S)'-4-{[(pyridin-4-yl­methyl­idene)hydrazinyl­idene}meth­yl]pyridine-κN1)zinc(II): crystal structure and Hirshfeld surface analysis

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].
