Nitrido and imido complexes

The N-N and metal-N force constants resulting from normal coordinate analysis of the N2-, NNH-, NNH2-, and NNH3-complexes l ppe, 2 ppeF, 34ppeF, and 4 epeF as well as the nitrido and imido complexes 5, Ns and 6 pe C1 are graphically represented in Fig. 4 (15-17). Upon protonation of l pe to the NNH complex 2 peF, the N-N force constant decreases from...

Chromium corroles have been isolated as 6-coordinate Cr(III) and 5-coordinate Cr(IV/V/VI) oxo, nitrido, and imido complexes. The synthesis of Cr(tpfc)(py)2 (py = pyridine), which is oxidized to (oxo)Cr(tpfc) on standing in aerated solution, was reported in 2001 [78]. Cr(tfpc)(0) could be reduced by cobaltocene to give...
