Studies on the Metal Chelate Compounds of Phenazine Derivatives. XI. Metal Chelates of 1-Phenazinethiol

Abstract

The acid dissociation constant of 1-phenazinethiol and its metal chelate formation constants have been determined spectrophotometrically in a 50% (v/v) ethanol at 25±1°. Metal chelates of 1-phenazinethiol were synthesized, and the salient feature of infrared (IR) spectra of these chelates were discussed. Considering from the formation constant of zinc chelate and its IR spectrum, it may be suggested that zinc-sulfur linkage of the zinc chelate has covalent character.
