Mixed (phthalocyaninato)(tetranaphthylporphyrinato) terbium(III) triple-decker complex [(TNP)Tb(Pc)Tb(TNP)] (1) was synthesized by treating the half-sandwich complex [Tb(TNP)(acac)] (acac = acetylacetonate) with Li-2(Pc). Compound 1 represents the first sandwich-type complex containing tetranaphthylporphyrin ligand. This new triple-decker complex was characterized by MALDI-TOF mass, H-1 NMR, electronic absorption and IR spectroscopies. The molecular structure was determined by single crystal X-ray diffraction analysis confirming the symmetrical triple-decker structure with two outer TNP ligands and one inner Pc ligand. The static and dynamic measurements for the magnetic properties of complex 1 were conducted. The results indicate the slow relaxation and strong quantum tunneling of magnetization for this symmetrical Tb-Tb magnet.
