Synthesis, characterization and antitumor activity of novel octahedral Pt(IV) complexes.

Novel platinum(IV) complexes were synthesized having octahedral structure for new antitumor agents. The series of (1,4-butanediamine)Pt(IV) complexes of the type trans,cis-[PtA(2)Cl(2)(1,4-butanediamine)] (A=hydroxo 9, acetato 12, trifluoroacetato 13 as axial ligands) and trans-[PtA(2)(malonate)(1,4-butanediamine)] (A=hydroxo 16, acetato 17, trifluoroacetato 18) were synthesized and characterized by IR, NMR and elemental analysis. The molecular structures of 12, 13 and 18 have been determined by X-ray diffraction methods.
