英文摘要	a new class of (ch2)(n)-bridged indenyl-pyrazoles [4-{ind-(ch2)(n)}-rr'pzh] (ind = 1h-inden-3-yl, n = 1-3, rr'pz = 3,5-disubstituted pyrazolato) were synthesized. reactions of the indenyl-functionalized pyrazoles with nickelocene in refluxing toluene afforded trimetallic and dimetallic cyclopentadienyl nickel(ii) complexes, i.e., [cpni{4-(ind-(ch2)(n))-rr'pz}(2)](2)ni and [cpni{4-(ind-(ch2)(n))-rr'pz}](2), depending on the steric hindrance from the 3,5-disubstituents on the pyrazolato rings. in the cpni(ii) complexes, pyrazolato ligands exhibit mu-eta(1): eta(1) coordination to the metal centers and the indenyl moieties demonstrate no interaction with the metals. all the indenyl-pyrazoles and their complexes were characterized by spectroscopic and analytical methods including x-ray crystallographic study.
