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

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.
