readily hydrated to give the corresponding amidato complex [(L3)Pd2(NHCOMe)]2+ (11). All complexes were isolated as perchlorate salts and studied by infrared, 1H, and 31P NMR spectroscopy. In addition, complexes 4[ClO4]·EtOH, 5[ClO4]2, 9[ClO4], 10[ClO4]·EtOH, and 11[ClO4]2·MeCN·MeOH have been characterized by X-ray crystallography. The dipalladium complex 4 was found to catalyse the vinyl-addition polymerization
