N2 - Deprotonation of the methylene group in bis(3,5-diisopropylpyrazol-1-yl)methane with nBuLi and reaction with carbon dioxide yields lithium bis(3,5-diisopropylpyrazol-1-yl)acetate (1). Treatment of 1 with ZnCl 2 results in the compound bis[bis(3,5-diisopropylpyrazol-1-yl)acetato]zinc(II), [Zn(C20 H31 N4 O2)2] (2), whose structure has monoclinic (P2 1/c) symmetry. The Zn II ion resides on an inversion center and is coordinated by two bis(3,5-diisopropylpyrazol-1-yl)acetate (bdippza) ligands. Each ligand facially coordinates the zinc center via κ 3 N,N′,O coordination modes to form a distorted octahedral complex with four pyrazole N atoms in the basal plane and two carboxylate O atoms in the axial sites.
