ABSTRACT:

A Cu(II) bimetallic ferrocene-thiosemicarbazone-based ligand complex* containing a phenyl fragment has been synthesized and analyzed. Paramagnetic Shift studies of 1H NMR and 13C NMR have been conducted on the complex. A comparison has been made with a similar that containing a methyl fragment. It has been found that whereas the Cu(II) paramagnetic influence may shift or even block the 1H NMR signals of the ligand in the complex, it completely inhibits the appearance of 13C NMR signals in the complexes studied. * Structure of ligand LH is given in Fig. 1.
