Abstract: | The tetradentate N2S2 Schiff base ligand 3,3′‐2,2′‐(ethylenedioxy)dibenzylidene]bis(S‐methyl dithiocarbazate) (H2L), prepared by the condensation of S‐methyl dithiocarbazate with 1,4‐bis(2‐formylphenyl)‐1,4‐dioxabutane in a 1:2 molar ratio, reacts with nickel acetate to form the title neutral metal complex, Ni(C20H20N4O2S4)]. The X‐ray structure of the complex shows a distorted square‐planar geometry around the Ni atom. The monomeric units are weakly associated into dimers via a long Ni?S interaction 3.569 (1) Å]. These dimeric units are then linked by C—H?S intermolecular contacts to form a polymeric chain along the a axis. |
