Synthesis and structural characterization of the Re3 triangular 4,4′-bipyridinium aqua-tris(μ-triiodo)-octachlorotrirhenium dihydrate complex

The Re3 cluster compound (4,4′-bipyH2) Re3Cl8I3H2O · 2H2O was obtained by thermal reaction of (NH4)4[Re2OCl10] with 4,4′-bipirydine triiodide. The structure of this compound has been established by X-ray measurement. This is the three-centre rhenium cluster with Re centres bonded by iodide bridges. The cations and anions positions are stabilized by hydrogen bonding network.
