中文摘要	a series of titanium and zirconium complexes based on aminoiminophosphorane ligands [ph2p(nt-bu)(nr)](2)mcl2 (4, m = ti, r = ph; 5, m = zr, r = ph; 6, m = ti, r = sime3; 7, m = zr, r = sime3) have been synthesized by the reaction of the ligands with ticl4 and zrcl4. the structure of complex 4 has been determined by x-ray crystallography. the observed very weak interaction between ti and p suggests partial pi-electron delocalization through both ti and p. the complexes 4-7 are inactive for ethylene polymerization in the presence of modified methylaluminoxane (mmao) or i-bu3al-ph3cb(c6f5)(4) under atmospheric pressure, and is probably the result of low monomer ethylene concentration and steric congestion around the central metal.
