Structural and spectral studies of nickel(II), copper(II) and cadmium(II) complexes of 3-furaldehyde thiosemicarbazone

The synthesis and characterisation of Ni(II), Cu(II) and Cd(II) complexes of 3-furaldehyde thiosemicarbazone (3FTSC) are reported. The crystal structure of the complex [Cu(3FTSC)2] is described. In Cu(II) and Ni(II) complexes, the metal ion is coordinated through the S and the N-azomethine atoms while in the Cd(II) complexes the coordination occurs through sulphur and furanic oxygen atoms.
