The reaction of thiosemicarbazide (NH2.NH.CS.NH2) with [Rh(CO)2Cl2]n in THF gives an air stable, off white solid Ru(CO)2Cl2.NH2.NH.CS.NH2. The ligand acts as bidendate and its has been suggested that it coordinates to the metal through N(1) and S atom. Also the salt [Ru(CO)2Cl2]n reacts with an excess of sodium acetylacetonate in THF and gives very stable red solid Ru(CO)2(acac)2xH2O. Similar product is obtained when [Ru(CO)2Cl2]n is treated with acetylacetone in presence of a base such as triethylamine. The complexes were characterised by IR, NMR and elemental analyses.
