title: Synthesis and Structure of Alkylzinc 3,5-Diphenylpyrazolates: Dramatic Influence of Steric and Solvent Effects.
abstract: The reaction of R2Zn (R = Et, (t)Bu) with 3,5-diphenylpyrazole results in the formation of three structurally diverse alkylzinc pyrazolates: a novel dinuclear tetrahydrofuran solvate, an unprecedented trimeric structure, and a spiro trinuclear aggregate. Structural analysis of the resulting complexes provides a new look at the aggregation and stabilization of alkylzinc species.
