Abstract

Abstract Complexes ML 1 2 and ML 2 2, with M = Fe II, Co II, Ni II, and 1,3-bis(2-R-tetrazol-5-yl)triazenide ligands L 1 (R = Me) and L 2 (R = tBu), have been synthesized by the reaction of corresponding 1,3-bis(2-R-tetrazol-5-yl)triazenes with metal(II) salts in basic media and characterized by IR, UV–Vis spectroscopy, thermal and X-ray diffraction analyses. Both 1,3-bis(2-R-tetrazol-5-yl)triazenes were found to deprotonate on coordination and act as tridentate chelating ligands forming distorted MN 6 octahedra around metal(II) cations.
