The Way

A star-shaped array, consisting in four tetraphenylporphyrin fused to a phthalocyanine central unit by pyrazine groups, is constructed via the condensation reaction of a dicyanoquinoxaline annulated to a porphyrin ring. The nature of the annulated group is critical for the success of the reaction; in the case of smaller linkers, such as a dicyanopyrazine unit, a nucleophilic substitution occurred, giving the corresponding alcoxy derivative in alcoholic solvents. The visible spectrum of the array shows the typical absorptions of the macrocyclic sub units. The synthetic pathway here presented opens the way to the preparation of [Formula: see text]-fused porphyrin-phthalocyanine arrays.

Herein we report the synthesis and characterization of a novel bis-tridentate 1,3,4-thiadiazole ligand (L = 2,5-bis[(2-pyridylmethyl)thio]methyl-1,3,4-thiadiazole). Two new mononuclear complexes of the type [MII(L)2](ClO4)2 (with M = FeII (C1) and CoII (C2)) have been synthesized, containing the new ligand (L). In both complexes the metal centers are coordinated by an N4S2-donorset and each of the two ligands is donating to the metal ion with just one of the tridentate pockets. The iron(II) complex (C1) is in the low spin [LS] state below room temperature and shows an increase in the magnetic moment only above 300 K. In contrast, the cobalt(II) complex (C2) shows a gradual spin crossover (SCO) with T1/2 = 175 K. To our knowledge, this is the first cobalt(II) SCO complex with an N4S2-coordination.
