Studies on N2 activation by transition metal hydride complexes are of particular interest and importance, but studies on well-defined N2 metal hydride complexes are still very limited. We report the synthesis and diverse transformations of a N2 dititanium hydride complex bearing the rigid acridane-based acriPNP-pincer ligands. This complex enabled N2 cleavage and hydrogenation even without additional reagents. Furthermore, diverse transformations of the N2 unit with a variety of organometallic compounds have been well established at the rigid acriPNP-ligated dititanium framework. This work has revealed many unprecedented aspects of N2 reaction chemistry, and may help open a new avenue for the design and synthesis of well-defined metal hydride complexes for N2 fixation and transformation.
