Copper(II) complexes with a novel tris(3,5-diisopropyl-1-pyrazolyl)methane ligand, [Cu(X2){HC(3,5-iPr2pz)3}] (XCl and NO3)

The synthesis of a novel tris(3,5-diisopropyl-1-pyrazolyl)methane ligand, HC(3,5-iPr2pz)3, is described; the structures of chlorocopper(II) and nitratocopper(II) complexes with its ligand have been determined by X-ray crystallography and compared with those of the related copper(II) complexes with HB(3,5-iPr2pz)3−.
