Low-valent gallium, indium, and tin compounds that contain a highly fluorinated tris(pyrazolyl)borate ligand: Syntheses and characterization of [HB(3,5-(CF3)(2)Pz)(3)]Ga, [HB(3,5-(CF3)(2)Pz)(3)]In, and [HB(3,5-(CF3)(2)Pz)(3)]Sn(CF3SO3)
Syntheses and characterization of gallium(I), indium(I), and tin(II) complexes of the [HB(3,5-(CF3)(2)Pz)(3)](-) ligand (where [HB(3,5-(CF3)(2)Pz)(3)](-) = hydrotris(3,5-bis(trifluoromethyl)pyrazol)borate)) are reported. X-ray crystal structures of [HB(3,5-(CF3)(2)Pz)(3)]In and [HB(3,5-(CF3)(2)Pz)(3)]Sn(CF3SO3) 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-(CF3)(2)Pz)(3)]Ga are very similar to those of the indium(I) analogue suggesting similar solution structures.
