Abstract
The reaction of the anion [Re4(μ-H)6(CO) 12]2- with acids affords the unsaturated (58 valence electron) anion [Re4H5(CO)12]-, which contains a distorted tetrahedral cluster, with Re-Re bond lengths in the range 2.857(1)-3.251(1) Å, bearing three edge-bridging and two face-capping hydride ligands, completely fluxional in solution down to -90 °C.
