摘要

Reaction of CrCl_3(THF)_3 with K[HB(pz)_3]in THF leads to the formation of the complex K[CrCl_3{HB(pz)_3}](1).The salt metathesis of complex 1 with[Ph_4P]Br in CH_2Cl_2 yields the complex[Ph_4P][CrCl_3{HB(pz)_3}](2).The structure of complex 2(centre dot)CHC1_3 has been determined by single crystal X-ray diffraction.In the anion the metal centre shows a distorted octahedral geometry with the hydrotris(l-pyrazolyl)borate bonded as N,N',N"-donor tripod ligand and three chloride atoms completing the co-ordination sphere.Complex 2 in the presence of MAO leads to the formation of an active catalyst for the polymerization of ethylene.
