摘要：

PALLADIUM complexes of (4-methoxyphenyl benzopyran, 4-fluorophenyl benzopyran and 4-(2-chloro-5-nitro) phenyl benzopyran ligands) have been synthesized and characterized using different tools such as IR, UV/ Vis, H-1-NMR, elemental analysis, thermal analysis, and mass spectroscopy. The mode of binding Pd (II) ion with the ligands shows that the Pd (II) ion binds with the ligands through the amino group nitrogen atom and cyanide group nitrogen atom of the ligands which revealed a square-planar coordination geometry at the metal center [Pd L-1.2Cl] 0.5H(2)O,[Pd L-2.2Cl] 1.5H(2)O and [Pd L-3.2Cl].
