New complexes of cerium(III) and neodymium(III) with coumarin-3-carboxylic acid (HCCA) were synthesized and characterized. The elemental, DTA and TGA analyses showed the general formula, Ln(CCA) 2 (NO 3 )(H 2 O) (Ln=Ce, Nd). To suggest the binding mode of HCCA a detail vibrational investigation based on Raman, FTIR and DFT/B3LYP/SVP studies of HCCA, its deprotonated form (CCA...
