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.

AbstractIn contrast to the reaction of cyclopentadienyl and (tris(pyrazolyl)borato)titanium(IV) chlorides with hydrazines which results in the formation of hydrazido titanium(IV) species the corresponding Ti(IV) complex (I) yields the title Ti(III) complexes (III) and (IV) (for (IV) no yield given).

Benzoato[hydrotris(3-phenylpyrazol-1-yl-N2)borato]zinc(II)
Acta Crystallographica Section C Crystal Structure Communications, 1995The structure of the title complex, [Zn{HB(C 9 H 7 N 2 ) 3 }(C 7 H 5 O 2 )], has been determined ; the central Zn atom is coordinated in a distorted tetrahedral environment by three N atoms, one from each pyrazole ring [Zn-N 2.038(5)-2.084(5) A], and by a benzoate O atom [Zn-O 1.935 (5) A].

Paramagnetic nitrile complexes of tris{3,5-dimethylpyrazolyl}borato nitrosyl molybdenum
Polyhedron, 1996Abstract The nitrile complexes [Mo(NO)Tp * I(NCR)] (R = Me, Pr n and CH 2 CH 2 -CH 2 CN), obtained by reaction of [Mo(NO)Tp * I 2 ] with the nitrile at room temperature, are paramagnetic (one unpaired electron), exhibiting characteristic EPR spectra and undergoing, electrochemically, an irreversible reduction process.
