摘要

Four new charge transfer salts based on tetrathiafulvalene (TTF) or tetramethyltetraselenafulvalene (TMTSF) donors and transition metal complexes [M(dcdmp)(2)] (dcdmp = 2,3-dicyano-5,6-dimercaptopyrazine), TMTSF5[Cu(dcdmp)(2)](4) (1), (TMTSF)(2)[Ni(dcdmp)(2)] (2), and (TTF)(7)[M(dcdmp)(2)](6) (M = Au (3) and Cu (4)) were prepared by electrocrystallization. These compounds are characterized by a rich variety of crystal structures with unusual donor/acceptor stoichiometries. In spite of the uncommon structural types observed, these salts can be highly conducting. Compound 1 crystallizes with segregated TMTSF stacks, showing 1D metallic properties with a room temperature conductivity of 134 S/cm. Compound 2 crystallizes in an out-of-registry mixed column arrangement of donor dimers and acceptors. Compounds 3 and 4 appear in single crystal X-ray diffraction as isostructural and composed of columns of TTF hexamers that are disrupted by a single TTF layer and surrounded by [M(dcdmp)(2)](-) monoanionic pairs, aligning perpendicularly to the hexamer stacks. However, measurements of the electric transport properties in single crystals suggest the existence of two phases. While phase 2 has a semiconducting behavior, phase 1 is clearly more conductive with copper complex 4 presenting a metal semiconductor transition around 210 K and room temperature conductivity of similar to 210 S/cm.
