摘要

Two tetrapyridyl ligands of 1,2,4,5-tetraethynyl(4-pyridyl) benzene (tpeb) and tetra(4-pyridyl)-tetrathiafulvalene (TTF(py)(4)) were used to react with trinuclear (Re(CO)(4))(3)(C3N3S3)(C3N3S3 = cyanurate trianion) moieties to afford hexanuclear [(Re(CO)(3))(6)(tpeb)(2)(C3N3S3)(2)]center dot 4CH(3)CN center dot toluene (1) and dodecanuclear [(Re(CO)(3))(12)(TTF(py)(4))(3)(C3N3S3)(4)]center dot 8CH(3)CN center dot 12DMF (2) boxes, respectively, under solvothermal conditions. Surprisingly, similar tetrapyridyl ligands with different core units (i.e., benzene and tetrathiafulvalene moieties) led to dramatically different structural motifs (i.e., hexanuclear and dodecanuclear boxes). Complex 1 forms a slightly bent trigonal-prismatic structure, containing two mu(3)-tpeb ligands and two Re3C3N3S3 moieties as well as a pi center dot center dot center dot pi interaction distance of 3.86 angstrom. It is noted that complex 2 features a novel four-star structure, and three crossed tetrathiafulvalene moieties from three mu(4)-TTF(py)(4) ligands to form a triple-decker arrangement with a pi center dot center dot center dot pi interaction distance of 3.70 angstrom. Moreover, 1 and 2 display luminescence properties in the solid state along with electrochemical properties for complex 2 arising from the electroactive TTF core.
