The newly synthesized complexes 2 and 3 were prepared by reacting the cyclopalladated Nile Red acetato-bridged dimer [(NR)Pd(l-OAc)]2 with the
appropriateb-diketonate ligand and the expected molecular structure (Chart 1) confirmed by mass spectra, IR
and
1
H NMR spectroscopies and by elemental analysis
(Experimental).
