Synthesis and characterization platinum (IV) complexes containing phthalazine ligands

Platinum (IV) complex   3 3 [PtMe phth ] X   ,1, has been prepared from the reaction of trimethyl platinum (IV) complex 3 [PtMe I] and 3 equivalents phthalazine. Complex 1 characterized using NMR spectroscopy and X-ray crystallography. Complex 1 in solid state shows yellow emission upon excitation under UV-lamp. The crystal structure of 1shows coordination of three phthalazine ligand to the platinum center. As shown in equation 1 complex 1 has three coordinated nitrogen atoms that providing the possibilityof coordination to the second metal center. Attempts for preparation hetero binuclear complexes containing bridging phthalazine ligand using 1 and other late transition metals are in progress in our group.[1]
