Abstract:
The infrared absorption of samarium (di-isopropoxy) mono dibenzoylmethide [Sm (ΟΡ r i ) 2 DBM] and samarium tris dibenzoylmethide [Sm(DBM) 3 ] in the region 4000 - 250 cm -1 have been studied. About 25 bands in each chelate have been observed and assigned to different modes of vibrations. The number of metal-oxygen vibration modes of the chelates suggest Vh and D 3 sym. metries for Sm (OP r i ) 2 DBM and Sm (DBM) 3 respectively. The relative frequency shifts of CO and CC stretching modes indicate that the metal-oxygen bonding in Sm(DBM) 3 is relatively stronger than in Sm (OP r i ) 2 DBM.
