[Abstract] Three tri-nuclear cobalt complexes ([Co3(tpa)3(L)](BF4)4 (1) (tpa=tris(2-pyridylmethyl)amine),[Co3(Metpa)3(L)](BF4)4 (2) (Metpa=(6-methyl-2-pyridylmethyl)bis(2-pyridylmethyl)amine) and [Co3(Me2tpa)3(L)](BF4)3 (3) (Me2tpa=bis(6-methyl-2-pyridylmethyl)(2-pyridylmethyl)amine)) with 2,3,6,7,10,11hexahydroxytriphenylene (H6L) and three spieces ancillary ligands have been prepared. Tri-nuclear mixed-valence Co complex (3) is prepared from methanol solution. Complex (3) has consist in that the valence of two cobalt ions have +III,one cobalt ion has +II and the tris-dioxolene bridging ligand is formally in the -5 [cat,cat,sq] oxidation state. Complex (3) shows evidence of temperature dependence of the charge distribution, displaying thermally induced valence tautomeric transition from {(ls-CoIII)2(hs-CoII)}-L(cat,cat,sq) to {(ls-CoIII)(hs-CoII)2}-L(cat,sq,sq) in both solid and solution states. On the other hand, complex (1) and complex (2) are stable in the entire temperature range investigated.Various-temperature magnetic susceptibility data for the compound displayed little variation in the range 2-380 K, and the reason caused the distinct charge distribution on Co-L (L: bridging ligand) by the natural rigidity of the tripodal ligands. These results appeared methylation of the 6-position of the pyridine rings in ancillary ligand effect on redox state in the complex, occuring the distribution of electrons between the cobalt centers and the bridging ligand. |
