The paper explores the capability of [(dppf)Pt(H-nbu2-DTO)]Cl (2) (dppf = 1,1′-diphenylphosphinoferrocene; H-nbu2-DTO = di-nbutyl-dithioxamidate) to act as a starting module for heterometallic linear chains. Actually, the reaction of 2 with [RuCl2(p-cymene)]2 affords the heterotrimetallic complex [Cl(p-cymene) Ru(μ-nbu2-DTO κ-N,N Ru κ-S,S Pt)Pt(dppf κ-P,P Pt) ]2 (4). However 2, allowed to stand, provides a blue compound of formula [(dppf)Pt(H-nbu2-DTO)]nCln (3), the most reliable value of n being 6. The oxidation behavior of the new species 2-4 has also been investigated. In particular, the oxidation behavior of cyclic compound 3 is quite unusual, and suggests a large delocalization of the HOMO over the whole multicomponent molecule.
