文摘
The synthesis of a new sandwich lutetium(III) bisphthalocyanine substituted with hexylthio groups (1), [(C6H13S)8Pc]2Lu, is described. The compound is very soluble in most common organic solvents and has been fullycharacterized (elemental analysis, IR, 1H and 13C NMR, UV-vis spectroscopy, mass spectrometry). The chemicallyoxidized and reduced forms have been formed and characterized. The crystal structure of the compound (1) hasbeen determined by X-ray diffraction on a single crystal. It crystallizes in the monoclinic space group C2/c witha = 31.558(2) Å, b = 32.755(2) Å, c = 20.489(1) Å,

, and Z = 4. The temperature dependenceof the magnetic susceptibility, measured on polycrystalline samples and in the range 6-300 K, is in agreementwith one unpaired electron per molecular unit as found for the unsubstituted derivative. The magnetic results canbe modeled assuming one-dimensional chain of spin S = 1/2 with g = 2.04 and an antiferromagnetic coupling (J= -11.83 cm-1, H = -2J
SiSj).
