reported for this type of complex. The second compound, Re2(hpp)3Cl3, 2, has three bridging hpp ligands, two equatorial chloride ions and one axial chloride ion. The Re–Re distance is 2.189(2) Å. The electronic structure of 1 has been determined by DFT calculations, the first time this has been done on a paddlewheel complex containing a third row transition element.
