Self-assembled heteroleptic Zn(II) dithiocarbamate-based 2d-interwoven supramolecular giant macrocycles and their redox properties

This article presents a new heteroleptic Zn(II) dithiocarbamate (1) having molecules linked together via H⋯H and π⋯π interactions to form a giant hexanuclear macrocycle. These macrocycles are connected together through S⋯H interactions to offer a unique two-dimensional cloth-like interwoven architecture in the solid state. The redox behavior of the complex deposited on the surface of a glassy carbon electrode was investigated in different pH media. The analyte was found to oxidize and reduce in a pH-dependent irreversible manner. On the basis of the electrochemical findings, redox mechanistic pathways were proposed.
