Low-Valent Gallium, Indium, and Tin Compounds That Contain a Highly Fluorinated Tris(pyrazolyl)borate Ligand: Syntheses and Characterization of [HB(3,5-(CF_3)_2Pz)_3]Ga,[HB(3,5-(CF_3)_2Pz)_3]In, and [HB(3,5-(CF_3)_2Pz)_3]Sn(CF_3SO_3)

摘要

Syntheses and characterization of gallium(I),indium(I),and tin(II) complexes of the [HB(3,5-(CF_3)_2Pz)_3]~- ligand (where [HB(3,5-(CF_3)_2Pz)_3]~- = hydrotris(3,5-bis(trifluoromethyl)pyrazolyl)borate))are reported. X-ray crystal structures of [HB(3,5-(CF_3)_2Pz)_3]In and [HB(3,5-(CF_3)_2Pz)_3]Sn(CF_3SO_3) show monomeric structures in the solid state. The In-N and Sn-N bond distances are longer than the corresponding bond distances of nonfluorinated analogues. NMR data of the gallium(I) adduct [HB(3,5-(CF_3)_2Pz)_3]Ga are very similar to those of the indium(I) analogue suggesting similar solution structures.
