to give [[graphic omitted]Ph2-2)(OMe)2-4,5}2Cl2](8; R = Ph, M = Pd). The complex [PdCl2(NCPh)2] with the bulky crown phosphine Q′ gives a mixture of trans-[PdCl2Q′2] and the corresponding cyclometallated complex; the complex (8; R = But, M = Pd) has also been prepared. A similar but more extensive series of platinum complexes has been made including mononuclear species formed by splitting the chloride-bridged
