The Novel Hydrogen-Rich Binuclear Cobalt Complex Anion, [(CoH3)2H3]5-

Hydrogen reacts with a mixture of cobalt bromide and phenylmagnesium bromide to yield a novel cobalt hydride species. EXAFS analysis reveals a binuclear cobalt hydride complex comprising three absorbers, principally a Co-Co centre, and also two types of supporting hydride ligands. Further, DFT, XANES, 1H NMR spectra and elemental analyses also support the title formulation
