Abstract | {The reactions of nickelocene with pyrazoles in benzene solution have resulted in the isolation of either dimeric compounds, [CpNi(mu-pzā)](2), (room temperature conditions) or trimetallic complexes, [CpNi(mu-pz āā)(2)](2)Ni, (elevated temperature conditions). Both dimeric and trimetallic species were obtained as red crystalline materials and X-ray structural investigations are reported for representative samples of each type. Structural features are interpreted and compared with similar, previously reported, nickel pyrazolate structures. Crystals of [CpNi(3,5-diMepz)](2) (C20H24N4Ni2), 1, are orthorhombic |
