Abstract | Two heterotrinuclear oligomeric complexes [trans-RuCl(C≡ Cpy-4)(dppm)2]2[MCl2] (M = Pd 2; M = Pt 3) are prepared from the metalloligand trans-[RuCl(C≡ Cpy-4)(dppm)2] (dppm = Ph2PCH2PPh2, 1). The resultant linear alignment of the metals [Ru-M-Ru] is imposed by a combinative use of trans-directed spacers and planar metals with trans-juxtaposed donor sites. Ligand exchange of 1 with [Pd(CH3CN)4][PF 6]2 gives trans-[Ru(CH3CN)(C≡ Cpy-4)(dppm)2][PF6] (4). All complexes are characterized by single-crystal X-ray crystallography and solution spectroscopy. Acid-base titration on 1 suggested protonation of the pendant pyridyl. Complexes 2 and 3 also undergo protonation at the C≡C moiety under acid conditions. The inter-conversion of alkynyl and vinylidene functionality is described. The dual acid and base characters of 4 makes it a potential metalloligand towards basic and acidic fragments in multinuclear heterometallic assemblies. © The Royal Society of Chemistry 2008. |
