context_page_description: In coordination chemistry and organometallic chemistry, transition metal imido complexes is a coordination compound containing an imido ligand. Imido ligands can be terminal or bridging ligands. The parent imido ligand has the formula NH, but most imido ligands are have alkyl or aryl groups in place of H. The imido ligand is generally viewed as a dianion, akin to oxide.
context_section_description: In some terminal imido complexes, the M=N-C angle is 180º but often the angle is decidedly bent.  Complexes of the type M=NH are assumed to be intermediates in nitrogen fixation by synthetic catalysts.
