Synthesis and Computational and Experimental Investigations of a para-Nicotinic Acid-Bridged Dirhenium(I) Dimer Complex.

ABSTRACT: The Re(I) dimer complex, [fac(CO)₃(phen)Re1-N(py)COORe2(phen)fac(CO)₃]⁺ (py = pyridine; phen = 1,10-phenanthroline), contains two different Re(I) centers 9.3 Å apart, one with a nitrogen donor and the other with an acetate donor from the bridging isonicotinate ligand. The complexes were characterized by ¹H NMR, UV-vis, fluorescence, and IR spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The absorption and emission properties of the dimer dominated by charge transfer transitions are analyzed with respect to those of the monomers, [fac(CO)₃(phen)Re-N(pyCOOCH₃)]⁺ and [fac(CO)₃(phen)ReOOCCH₃]. Spectral comparison of these three complexes
