Properties of Metal Carbonyls
1) Metal carbonyls are mostly solids at room temperature and pressure. Exceptions being iron and nickel carbonyls which are liquids.
2) The mononuclear carbonyls are volatile and toxic.
3) Most of metal carbonyls are soluble in hydrocarbon solvents except Fe2Co9
4) The mononuclear carbonyls are either colourless or light coloured.
5) They are highly reactive due to metal centre and the CO ligands.
6) Metal carbonyls are used as industrial catalysts and as precursors in organic synthesis.
