Synthesis and Characterization of Complex Compounds from Cadmium(II) Chloride and Cobalt(II) Chloride with N,N'-Diethylthiourea

The synthesis of ionic complexes cadmium(II) chloride and cobalt(II) with N,N'-diethylthiourea (detu) ligands has not been previously reported. Therefore, in this research, the was carried out to study structure characterization two complex compounds. cadmium(II)-detu synthesized using direct reaction method a ratio between Cd(II) salt detu ligand 1:2. Meanwhile, cobalt(II)-detu Co(II) 2:4. have melting points 105-108 ˚C 122-125 ˚C, respectively. electrical conductivity showed that were ionic. FTIR analysis shifting C=S functional group’s band smaller wavenumber, which indicates coordinating through S atom. indirect evidence from 1H-NMR CH3 CH2 only slightly shifted free Cd-detu Co-detu complexes.
