Modulation of the magnetic and photophysical properties in 3d-4f and 4f-4f' heterobimetallic complexes involving a tetrathiafulvalene-based ligand.

ABSTRACT: The reaction between the 2-(1-(2,6-di(pyrazol-1-yl)-4-methylpyridyl)-4,5-(4,5-bis(propylthio)-tetrathiafulvalenyl)-1H-benzimidazol-2-yl)-pyridine ligand (L), 1 equivalent of Ln(hfac)₃·2H₂O/Dy(tta)₃·2H₂O (hfac^- = 1,1,1,5,5,5-hexafluoroacetylacetonate, tta^- = 2-thenoyltrifluoroacetonate) and M(hfac)₂·2H₂O leads to the formation of heteroleptic 3d-4f dinuclear complexes of formula [MLn(hfac)₅(L)]_n (M(II) = Cd, Zn, Co, Mn, Ni and Ln(III) = Dy, Yb, Nd) and [ZnDy(tta)₂(hfac)₃(L)]·(CH₂Cl₂). Their X-ray structures reveal that the two coordination sites are occupied by one Ln(III) ion and one M(II) transition metal respectively. The
