AbstractA 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. (C) 2008 Elsevier B. V. All rights reserved.
