Complexes of 1,3-bis(2-thiazolylimino)isoindoline with middle and late first row transition metals

Abstract

In this communication, we present a study that probes the middle and late first row transition metal chemistry of 1,3-bis(2-thiazolylimino)isoindoline, adding to the known Fe and Cu compounds. Complexes of this ligand with Mn, Co, Zn and a new Fe form are presented and all are structurally characterized by single crystal X-ray methods. The 1,3-bis(2-thiazolylimino)isoindoline ligand can potentially bind via the thiazolyl nitrogen or sulfur atoms; in all of the complexes presented in this report, the N,N,N binding mode is observed exclusively. The ligands bind in a planar configuration, similar to that seen for bis(2-iminopyridyl)isoindoline. Herein, we present a study that probes the middle and late first row transition metal chemistry of 1,3 bis(thiazolylimino)isoindoline, adding to the known Fe and Cu compounds. Complexes of this ligand with Mn, Co, Zn, and a new Fe form are presented and are structurally characterized by X-ray methods. ►The metal binding chemistry of 1,3-bis(2-thiazolylimino)isoindoline has been extended to new first row transition metal ions. ►The ligand chelates as a monoanion in the N,N,N binding mode. ►The X-ray structure of the free ligand as well as Mn, Fe, Co and Zn complexes is reported.
