Resumo

The reaction of trichloro[tris(pyrazolyl)borato]titanium(IV) with hydrazines yields titanium(IV) hydrazido(1–)-species, whereas the corresponding derivative of 3,5-dimethylpyrazole yields titanium(III) compounds which do not contain hydrazine residues. The X-ray crystal structures of two of the latter products, trimethylhydrazinium trichloro[tris(3,5-dimethylpyrazolyl)borato]-titanate(III) and dichloro(3,5-dimethylpyrazole)[tris(3,5-dimethylpyrazolyl)borato]titanium(III), are described.
