Coumarin is found in a variety of plants such as Tonka bean, Lavender, sweet clover grass, Licorice and also occurs in food exists plants such as strawberries, apricots, cherries, cinnamon. Coumarin derivatives have blood-thinning, anti-fungicidal, anti-tumor and anticoagulant activities. Photophysics and photochemistry of coumarin derivatives are also important.[1] With reaction between 6-Aminocoumarin and pyridine-2-carboxaldehyde we synthesized N-[(2-pyridyl)methyliden]-6-coumarin (L) [2,3]. The ligand, L added to hexachloroplatinic acid to synthesize a Pt(IV) complex of formula [Pt(L)2]Cl6 and [Pd(L)2]Cl2. On the other hand, the reaction in the attendance of pyrocatechol has isolated [Pt(L)(1,2-dihydroxybenzene)2]Cl6. The compound is characterized by FTIR, UV–Vis and 1H NMR spectroscopic data.
