摘要：

The poly(pyrazolyl)borate family of ligands has been used to prepare a variety of stable complexes of gallium and indium of the general formula [poly(pyrazolyl)borate](m)MCl(n)(CH3)(p) (m + n + p = 3), and the cationic complexes {[poly(pyrazolyl)borate](2)M}(+). The results of these studies show that in complexes of potentially multidentate poly(pyrazolyl)borate ligands these two metals prefer four- or six-coordination. The only five-coordinate complexes, [H2B(pz)(2)](2)MX, that have been prepared contain the dihydrobis(pyrazolyl)borate ligands. These complexes, even the organometallics, are unusually stable. The complex [HB(3,5-Me(2)pz)(3)]InCl2(THF) is an excellent starting material for the formation of complexes containing one poly(pyrazolyl)borate ligand and other types of ligands and also intermetallic complexes. A bulky poly(pyrazolyl) borate ligand stabilizes indium(I) in the complex [HB(3-Phpz)(3)]In.
