  Platinum(II) diamine with N,N-dimethylethylenediamine (N,N-dimeEn) [Pt(CH(3))(2)N(CH(2))(2)NH(2)}Cl(2)] (I) was synthesized. The reaction of the diamine with pyridine gave Pt(II) tetramine [Pt(CH(3))(2)N(CH(2))(2)NH(2)}Py(2)]Cl(2) (II), which was oxidized with chlorine to give Pt(IV) triamine Pt[(CH(3))(2)N(CH(2))(2)}PyCl(3)]Cl center dot H(2)O (III). The reaction of III with chlorine (chloroamidation) yielded chloroimide [Pt(CH(3))(2)N(CH(2))(2)NCl}PyCl(3)] (IV). The IR spectra of complexes I-IV and UV/Vis spectra of III and IV were studied. X-Ray diffraction analysis was performed for III (monoclinic crystals, space group P2(1)/c, a = 7.7437(6), b = 8.1100(7), c = 28.52992(2) angstrom, beta = 93.7280(10)degrees, Z = 4, R(hkl) = 0.0420) and IV (orthorhombic crystals, space group Pna2(1), a = 15.7825(12), b = 7.4447(6), c = 12.3099(6) angstrom, Z = 4, R(hkl) = 0.0539). During oxidation of Pt(II) tetramine with chlorine, the pyridine molecule is removed from the cis position relative to the (CH(3))(2)N group (trans position relative to the NH(2) group) of N,N-dimethylethylenediamine. The reaction of chloroimide complex IV with concentrated HCl (dechloroamidation) at 20 degrees C afforded the initial complex III; that at 100 degrees C, gave triamine III together with Pt(IV) diamine [Pt( N,N-dimeEn)Cl(4)] (V) (monoclinic crystals, space group P2(1)/n, a = 7.1278(5), b = 11.5384(8), c = 12.7501(9) angstrom, beta = 93.23(10)degrees, Z = 4, R(hkl) = 0.0239).
