cyclometallated complex [Pd2,3,4-(MeO)3C6HC(H)=N(2-O-5-(BuC 6 H 3 )}] 4 (la) with the tridentate ligand [C,N,O]. The complex showed a tetranuclear arrangement of the cyclometallated monomers with a P 4 O 4 core. Reaction of 2,6-(Me)2C6H3C(H)=N[2-(OH)C 6 H 4 ] (b) and 2,5-(Me)2C6H3C(H)=N[2-(OH)C 6 H 4 ] (c) with palladium(II) acetate under similar conditions yielded the tetranuclear complexes [Pd 6 -Me
