Two new dinuclear and two new trinuclear complexes of 2,3,7,8,12,13,17,18-octakis(methylthio)tetraazaporphyrinatomagnesium(II), [Mg(OMTTAP)] were synthesized using a convenient stepwise process. These complexes possess (bpy)2RuII and Cp(PPh3)RuII metal moieties directly attached to the β-positions in the [Mg(OMTTAP)] through thioether chelation. Complexes were characterized using 1H-n.m.r., u.v.–vis and mass spectroscopic data. The peripheral binding of the two RuII units significantly influenced redox potentials of the OMTTAP core by lowering E1/2 for the OMTTAP centered oxidation and reduction processes, both, as evident from their cyclic voltammograms. The stepwise synthesis reported here demonstrates success of a convenient strategy to obtain hybrid, trimetallic, redox active chromophores with linear and bent motifs.
