Abstract

The possibility of forming molecular Ag(I) complexes with tris(3,5-dimethylpyrazol-1-yl)methane (HC(3,5-Me₂pz)₃) and fluorinated β-diketones (hexafluoroacetylacetone (Hhfac) and trifluoroacetylacetone (Htfac)) is tested to expand the library of potential precursors for the chemical vapor deposition of Ag containing materials. It is established that the interaction of HC(3,5-Me₂pz)₃ with silver β-diketonates leads to the formation of [Ag{HC(3,5-Me₂pz)₃}₂]⁺ cationic complexes. At the same time, a stable desired product [Ag{HC(3,5-Me₂pz)₃}hfac] (L = hfac) was isolated and characterized. The structures of [Ag{HC(3,5-Me₂pz)₃}₂](tfac) and as series of solvates [Ag{HC(3,5-Me₂pz)₃}(hfac)]·½THF and [Ag{HC(3,5-Me₂pz)₃}₂](L)Solv_x (L = hfac, Solv = Et₂O (x = ¼), C₇H₈ (x = ½), CHCl₃ (x = 1); L = tfac, Solv = THF (x = 1)) are determined by XRD. Structures of the cationic and molecular complexes are compared with those of related compounds.
