Condensation of 1,2-dicyanobenzene and 2-amino-4-methylpyridine resulted in the formation of a ligand, 4′-MeLH, which in its anionic form functions as a tridentate chelate. Metal complexes were prepared with metal to ligand ratios of 1:1 and 1:2. The 1:1 complexes also contain acetate as a ligand while in the 1:2 complex the two tridentate ligands provide a pseudooctahedral environment about the metal ion. An analogous binucleating ligand was prepared by reaction of 1,2,4,5-tetracyanobenzene and 2-amino-4-sec-butylpyridine. This ligand, as a dianion, is capable of binding two metal ions, providing three coordination sites for each. Complexes were prepared in which the remaining coordination sites are occupied either by 4′-MeLH, resulting in two six-coordinate metal ions, or by an acetate ligand. Mononuclear and binuclear complexes were prepared with Mn(II), Fe(II), Co(II), Co(III), Ni(II), Cu(II), and Zn(II). Magnetic, spectral, and electrochemical properties of these molecules were investigated.
