Steps:
2 2.1.1 General procedure for the synthesis of the ligands (HL1-HL4)
General procedure: Synthesis of the ligands was carried out as per the literature methods [16,17] with slight modifications. 4-oxo-4H-chromene-3-carbaldehyde (0.5g; 2.871mmol) was dissolved in 10cm3 of ethanol. To this, ethanolic solution of thiosemicarbazide/4(N)-methylthiosemicarbazide/4(N)-ethylthiosemicarbazide/4(N)-phenylthiosemicarbazide (2.871mmol) was added and the mixture was refluxed for 2h. A white compound precipitated was collected by filtration and washed well with cold ethanol and dried in vacuo.
