The reaction of the Schiff base ligand 3,4-(OCH2O)C6H3C(H)=NCH2[3,4- (OCH2O)C6H3] (a) with Pd(OAc)2 yields two endocyclic cyclometallated compounds: [Pd{3,4-(OCH2O)C6H2C(H)=NCH2 [3,4-(OCH2O)C6H3]-C2,N}(μ-O 2CMe)]2 (C2,N-bonded) (1a), and [Pd{3,4-(OCH2O)C6H2C(H)=NCH2 [3,4-(OCH2O)C6H3]-C6,N}(μ-O 2CMe)]2 (C6,N-bonded) (1b), which may be separated by fractional crystallization. The corresponding cyclopalladated dimers with bridging chloride ligands, 2a, 2b, have been prepared by a metathesis reaction with aqueous sodium chloride. Treatment of the latter compounds with tertiary phosphines in the appropriate molar ratio gave the mono and dinuclear compounds, 3a-8a and 3b-5b, respectively. The structure of compound 1a has been determined by X-ray diffraction analysis. The molecular configuration is a dimeric form of the anti isomer with the cyclopalladated moieties in an 'open-book' arrangement linked by two acetate bridging ligands.
