Herein, we report the isolation of new heterobimetallic complexes [Ni 0.6 Pd 1.4 (EtCS 2 ) 4 ] ( 1 ), [NiPt(EtCS 2 ) 4 ] ( 2 ) and [Pd 0.4 Pt 1.6 (EtCS 2 ) 4 ] ( 3 ), which were constructed by using transmetallation procedures. Subsequent oxidation with iodine furnished the MM′X monodimensional chains [Ni 0.6 Pt 1.4 (EtCS 2 ) 4 I] ( 4 ) and [Ni 0.1 Pd 0.3 Pt 1.6 (EtCS 2 ) 4 I] ( 5 ). The physical properties of these systems were investigated and the chain structures 4 and 5 were found to be reminiscent of the parent [Pt 2 (EtCS 2 ) 4 I] species. However, they were more sensitively dependent on the localised nature of the charge on the Ni ion, which caused spontaneous breaking of the conduction bands.
