摘要：

New mononuclear nitratocopper(II) complexes ([Cu(NO3){HB(3,5-iPr(2)pz)(3)}] (1)(1) and [Cu(NO3){HB(3-tBu-5-iPrpz)(3)}] (3)) and a novel mononuclear hydroxocopper(II) complex ([Cn(OH){HB(3-tBu-5-iPrpz)(3)}] (4)) have been prepared. These complexes were characterized by X-ray analysis and IR, UV-vis, and EPR spectroscopies. Except for the dinuclear complex ([{Cu[HB(3,5-iPr(2)pz)(3)]}(2)(mu-OH)(2)] (2)), the complexes are mononuclear structures having square-pyramidal (1), trigonal-pyramidal (3), and distorted tetrahedral (4) geometry. In comparison with these structures and their physicochemical properties, the structural effects on the alkyl substitutions at the close 3-position in hydrotris-(pyrazolyl)borates play an important role in modifying the coordination environment about a copper(II) center and their physicochemical properties.
