Three novel Cd(II) dithiocarbamate complexes: synthesis, structural diversity and fluorescence properties

Three new homoleptic cadmium (II) dithiocarbamate complexes having molecular formula [Cd(KL)2], (KL1 = C15H13N1F1S2) (1); (L2 = C13H11N1F1S2) (2); (L3 = C11H14N1O1S2) (3), have been synthesized and characterized by elemental analysis, spectroscopy (IR, 1H and 13CNMR and UV–Vis). Single crystal X-ray studies confirm that the complex 1 crystallises in Orthorhombic with space group Pna21 and holding dimeric structure. In this complex Cd2+ having distorted octahedral geometry about the metal centre forms 1D coordination polymeric structures. The dimeric form of complex 2 and 3 crystallizes in triclinic crystal lattice with space group P-1.
