Abstract

Two novel compounds, [(μ-dppm)₂Cu₂(O₂CC₆H ₄CO₂)Cu₂(μ-dppm)₂](PF ₆)₂·3.4CH₂Cl₂ (1·3.4CH₂Cl₂) and [(μ-dppm)₂Cu₂(O₂CC₂F ₄CO₂)Cu₂(μ-dppm)₂](PF ₆)₂·5CH₂Cl₂ (2·5CH₂Cl₂), have been prepared from the reactions of [(μ-dppm)₂Cu₂(CH₃CN)₂](PF ₆)₂ with the corresponding dicarboxylate salts, and their structures have been determined crystallographically. The crystal structures of 1 and 2 consist of the complex cations [(μ-dppm)₂Cu₂(L-L)Cu₂(μ-dppm) ₂]²⁺, in which two dppm-bridged dinuclear copper(I) units are linked by dicarboxylate bridges L-L^2- (L-L = O₂CC₆H₄CO₂ and O₂CC₂F₄CO₂) in an end-to-end fashion, PF₆^- ions and dichloromethane molecules. The Cu···Cu separations within the [(μ-dppm)₂Cu₂]²⁺ units are 2.707(1) and 2.833(1) Å in 1 and 2, respectively. In both complexes, the copper(I) centers are in a trigonal coordination environment comprised by one O and two P atoms; additional contacts between the Cu centers and chlorine atoms of dichloromethane are observed in 2.
