Title: Expanding the Chemistry of Rhenium Metal–Metal Bonded Fluoro Complexes: Facile Preparation and Characterization of Paddlewheel Complexes

Abstract

Quadruply bonded rhenium(III) dimers with the stoichiometry Re 2L 4F 2 (1, L = hexahydro-2H-pyrimido[1,2a]pyrimidinate (hpp ); 2, L = diphenyl formamidinate (dpf )) were prepared from the solid-state melt reactions (SSMRs) between (NH 4) 2[Re 2F 8]·2H 2O and HL. Then those compounds were characterized in the solid state by single-crystal X-ray diffraction and in solution by UV–visible spectroscopy and cyclic voltammetry. The compound [Re 2(hpp) 4F 2]PF 6 (3) was prepared from the one-electron oxidation of Re 2(hpp) 4F 2 with [Cp 2Fe]PF 6. Compounds 1–3 are isostructural with the corresponding chloro derivatives. In summation, compound 1 undergoes two one-electron oxidations. Comparison with its higher halogen homologues reveals that Re 2(hpp) 4F 2 (1) is more easily oxidized than its chloro and bromo analogues.
