Abstract

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 ZnCl₂ results in the com­pound bis­[bis­(3,5-diiso­propyl­pyrazol-1-yl)acetato]­zinc(II), [Zn(C₂₀H₃₁N₄O₂)₂] (2), whose structure has monoclinic (P2₁/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 κ³N,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.
