Quadruply bonded rhenium(III) dimers with the stoichiometry Re2L4F2 (1, L = hexahydro-2H-pyrimido[1,2a]pyrimidinate (hpp–); 2, L = diphenyl formamidinate (dpf–)) were prepared from the solid-state melt reactions (SSMRs) between (NH4)2[Re2F8]·2H2O 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 [Re2(hpp)4F2]PF6 (3) was prepared from the one-electron oxidation of Re2(hpp)4F2 with [Cp2Fe]PF6. 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 Re2(hpp)4F2 (1) is more easily oxidized than its chloro and bromo analogues.
