2+1 Rhenium Tricarbonyl Complexes with N,N′-Bidentate Ligands and Ethyl Isocyanoacetate: Synthesis, Structure, and Properties

2+1 tricarbonyl complexes [Re(CO) 3 (N^N)CNCH 2 COOEt]X, where N^N = 2,2′-bipyridine (bipy) or 1,10-phenanthroline (phen) and X = Cl – or ClO 4 – , were prepared and isolated by two procedures. The intermediate tricarbonyl complexes [Re(CO) 3 (N^N)X] (where X = Cl – or ClO 4 – ) were also isolated. The composition and molecular structure of these complexes were determined by single crystal X-ray diffraction analysis. The complexes have fac -tricarbonyl structure with bidentate coordination of bipy and phen. The complexes were characterized by PL, IR, UV-Vis, and 1 H NMR spectroscopy and by elemental analysis.
