Crystal structure of a homoleptic zinc(II) complex based on bis-(3,5-diiso-propyl-pyrazol-1-yl)acetate.

ABSTRACT: Deprotonation of the methyl-ene group in bis-(3,5-diiso-propyl-pyrazol-1-yl)methane with nBuLi and reaction with carbon dioxide yields lithium bis-(3,5-diiso-propyl-pyrazol-1-yl)acetate (1). Treatment of 1 with ZnCl₂ results in the com-pound bis-[bis-(3,5-diiso-propyl-pyrazol-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-diiso-propyl-pyrazol-1-yl)acetate (bdippza) ligands. Each ligand facially coordinates the zinc center via κ³N,N',O coordination modes to form a distorted octa-hedral complex with
