Abstract
Ten [$Pd^{II}$(dicarboxylato)(1, 2-diaminocyclohexane)] complexes were prepared after the antitumor-active Pt(II)1, 2-diaminocyclohexane complexes as the cisplatin analogues of palladium series. They were characterized by means of elemental analysis, IR and NMR spectroscopy. As a result, the dicarboxylate ligands were conformed to be chelated with Pd(II) within the scope studied. The stability differences beween the dicarboxylato complexes according to the chelate ring size could not be differentiated due to generally lower thermodynamic stability of the dicarboxylato Pd(II) complexes.
