Abstract

Two new heterotrinuclear organorhenium(i) mercury(ii) derivatives of 4-ethynylpyridine [Re(CO)₃Cl(NC₅H₄C≡CHgMe)₂] 1 and [Re(CO)₃Cl(NC₅H₄C≡CHgC≡CC₅H₄N)₂] 2 were prepared in good yields by the reaction of Re(CO)₅Cl with a methylmercury(ii) derivative of 4-ethynylpyridine 1a and its inorganic mercury(ii) derivative, bis(4-pyridylethynyl)mercury 2a, respectively. The structures of these mixed-metal complexes were established by spectroscopic (FT-IR, NMR, and FABMS) techniques and their photophysical properties were examined in both fluid and solid phases.
