Two kinds of Pt mononuclear complex containing propyl or butyl amines, which can bind to second metals, have been synthesized.
As analogs of cis-[Pt(piam)2(NH3)2]·2H2O (1, piam=pivalamidate), two kinds of platinum mononuclear complexes, cis-[Pt(piam)2(NH2C3H7)2]·H2O (2) and cis-[Pt(piam)2(NH2C4H9)2] (3), have been synthesized and characterized by single-crystal X-ray analyses. The square-planar complexes 2 and 3 contain propyl and butyl moieties, respectively, enhancing the hydrophobicity. Both compounds have non-coordinated oxygen atoms in the piam ligands that can bind to a second metal, such as the Cu2+ ion, to afford trinuclear Pt–Cu–Pt complexes. UV–Vis and electron paramagnetic resonance spectra of the reaction of 2 and 3 with the Cu2+ ion show that both compounds form dinuclear Pt–Cu complexes as intermediates.
