Coordination Chemistry of 2,2 '-Bipyridyl- and 2,2 ':6 ',2 ''-Terpyridyl-Substituted BEDT-TTFs: Formation of a Supramolecular Capsule Motif by the Iron(II) Tris Complex of 2,2 '-Bipyridine-4-thiomethyl-BEDT-TTF

摘要

Molecules of tris(2,2'-bipyridine-4-thiomethyl-BEDT-TTF)iron(II) (BEDT-TTF = bis(ethylenedithio)-tetrathiafulvalene) assemble in pairs to form a novel supramolecular capsular structure in the solid state. Three BEDT-TTF residues from one complex lie in the three grooves between coordinated bipyridines of the other complex, and vice versa, to form a capsule with 3-fold rotational symmetry and an internal volume of ca. 160 angstrom(3). Further aspects of the coordination chemistry of this ligand, its 6-substituted isomer, and the 2,2':6'2"-terpyridy1-4'-thiomethyl-BEDT-TTF analogue are described.
