The chemistry of dinitrogen residues. Part 1. Diazenido-complexes of titanium, and some substituted analogues. X-Ray crystal structures of [Ti(C5H5)Cl2(NNPh)], [Ti(C5H5)Cl2(NCBunBut)], and [Ti(C5H5)Cl2(NPPh3)]
Abstract
The structures of [Ti(C5H5)Cl2(NCBunBut)], [Ti(C5H5)Cl2(NPPh3)], and [Ti(C5H5)Cl2(NNPh)] are described. The first two compounds contain NCBunBut and NPPh3 bound end-on with Ti–N double bonds which are rare. The last contains a unique side-on NNPh group. The NNPh can be removed from the complex as phenylhydrazine upon reaction with acid.
