the bimetallic complex [(PdCl)2-1,4-C6(CH2NMe2)4-2,3,5,6}] (15), whereas its reaction with [PtCl2(COD)] (COD = cycloocta-1,5-diene) or Me3SnCl gives the ionic tin(IV) species [(Me2Sn)2-1,4-C6(CH2NMe2)4-2,3,5,6}]2+(X-)2 with X being Cl (18a) or Me3SnCl2 (18b). The X-ray crystal structure of 18b has been determined and the molecular geometry found shows that the central dimetalated aryl ligand system
