Abstract
Interaction of 1-(2-pyridylazo)-2-naphthol (PAN) with [Mo(CO)6] in air resulted in formation of the tricarbonyl oxo-complex [Mo(O)(CO)3(PAN)], 1. The dicarbonyl complex [Ru(CO)2(PAN)], 3, was obtained from the reaction of [Ru3(CO)12] with PAN. In presence of triphenyl phosphine (PPh3), the reaction of PAN with either Mo(CO)6 or Ru3(CO)12 gave [Mo(CO)3(PAN)(PPh3)], 2, and [Ru(CO)2(PAN)(PPh3)], 4. All the complexes were characterized by elemental analysis, mass spectrometry, IR, and NMR spectroscopy. The thermal properties of the complexes were also investigated by thermogravimetry.
