Synthesis and characterization of the anion tetra-μ-hydridoiodopentadecacarbonyl tetrarhenate(1-)

The reactions of [H4Re4(CO)15]2- with ethanolic I2 gives the novel species [H4Re4(CO)15I]-, characterized by IR, NMR and X-ray analysis. The monoanion contains an open tetrametal array as in the parent species, with the iodide ligand terminally bound to the apical metal atom. The hydridic hydrogen atoms are bridging on the four ReRe bonds. © 1979.
