Abstract: Hetero-bimetallic complexes of a vanadium(V) and rhenium(VII) combination, connected by a μ-oxido bridge [LVO(μ-O)ReO3]·H2O (L = salen and its derivative) (1, 2), have been synthesized. Compounds undergo a vanadium-based single-electron reduction at E1/2 = 0.59 V (vs. Ag/AgCl reference) to generate catholyte solutions that display characteristic vanadium EPR at room temperature with eight-line pattern (51V, I = 7/2), each line being split into a doublet due to Re-superhyperfine coupling (A (185,187Re) = 20.7 × 10−4 cm−1).
