Graphical Abstract

A series of octahedral bis-3,6-di-tert-butylcatecholates based on tin(IV) containing metal coordinated substituted iminopyridines and diazabutadienes have been synthesized and structurally characterized. The compounds absorb in the visible region of the spectrum. Charge transfer between the catecholate donor and the diimine acceptor is responsible for the absorption. This was confirmed by DFT calculations and electrochemical studies performed by CV.

Abstract

A series of new octahedral bis-3,6-di-tert-butylcatecholates based on tin(IV) containing metal-coordinated N-donor ligands (substituted iminopyridines and diazabutadienes) has been synthesized and structurally characterized. The compounds, both solid and in solution, are intensely colored. They absorb in the visible region of the spectrum. Charge transfer between the catecholate donor and the diimine acceptor is responsible for the absorption. This observation is in good agreement with the DFT calculations and with the electrochemical studies carried out by CV.
