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 ...
