The triply bonded complexes (X = Cl or Br, dppm = Ph2PCH2PPh2) react with RNC (R = Me, Bu^t, or C6H3Me2-2,6) to yield the monoisocyanide adducts .The spectroscopic properties of these species are in accord with the presence of isomers in solution.Chemical oxidation of the neutral complexes to their corresponding paramagnetic monocations produces a single isomer in each instance.The solid-state structure of t)> has been shown to be that of the A-frame-like molecule t)>.The retention of a Re-Re multiple bond is supported by both structural work (Re-Re = 2.30 Angstroem) and a qualitative treatment of the bonding which is consistent with the presence of a slightly weakened triple bond.
