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 [Ru
3
(CO)
12
] with PAN. In presence of triphenyl phosphine (PPh
3
), the reaction of PAN with either Mo(CO)
6
or Ru
3
(CO)
12
gave [Mo(CO)
3
(PAN)(PPh
3
)], 2, and [Ru(CO)
2
(PAN)(PPh
3
)], 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.
