Abstract
Treatment of CrCl3(THF)3 with KPzTp in THF affords of the compound K[Cr(PzTp)Cl3], and the K+ in this complex can be replaced by Et4N+ in CH2Cl2. Well-defined green crystals of [Et4N]r(PzTp)Cl3] (I) suitable for X-ray diffraction are obtained at −20°C. In the anion the metal center shows a distorted octahedral geometry with the tetra(pyrazolyl) borate bonded as three N-donor tripod ligands and three chloride atoms completing the coordination sphere.
