Three organoplatinum(II) complexes bearing natural aryl-olefin and quinoline derivatives, namely, 4-meth-oxy-5-(2-meth-oxy-2-oxoeth-oxy)-2-(prop-2-en-1-yl)phen-ylplatinum(II), [Pt(CHO)(CHNO)], (), 4-meth-oxy-5-(2-oxo-2-propoxyeth-oxy)-2-(prop-2-en-1-yl)phen-ylplatinum(II), [Pt(CHO)(CHNO)], (), and chlorido-4-meth-oxy-5-(2-oxo-2-propoxyeth-oxy)-2-(prop-2-en-1-yl)phen-yl-plat-inum(II), [Pt(CHO)Cl(CHN)], (), were synthesized and structurally characterized by IR and H NMR spectroscopy, and by single-crystal X-ray diffraction. The results showed that the cyclo-platinated aryl-olefin coordinates with Pt the carbon atom of the phenyl ring and the C=C group. The deprotonated 8-hy-droxy-quinoline (CHNO) and quinoline-2-carb-oxy-lic acid (CHNO) coordinate with the Pt atom the N and O atoms in complexes () and () while the quinoline (CHN) coordinates the N atom in (). Moreover, the coordinating N atom in complexes ()-() is in the position compared to the C=C group. The crystal packing is characterized by C-H⋯π, C-H⋯O [for () and ()], C-H⋯Cl [for () and π-π [for ()] inter-actions.
