  摘要：

  The novel silver(I) coordination polymer with 2,5-bis(4',5'-bis(methylthio)-1',3'-dithiol-2'ylidene)-1,3,4,6-tetrathiapentalene (TTM-TTP), [Ag(TTM-TTP)(CF3SO3)](n) (1), which consists of 1-D waving chains, was synthesized and characterized. Polymer 1 can be also regarded as a 3-D supramolecular network formed via many shorter side-by-side and face-to-face (SS)-S-... contacts. This polymer and its iodine-doped compound 2 behave as semiconductors with σ(25°C) values of 7.1 x 10(-6) and 0.85 S cm(-1), respectively.[GRAPHICS]

  (TTM-TTP)AuI2 (TTM-TTP: 2,5-bis[4,5-bis(methylthio)-1,3-dithiol-2-ylidene]-1,3,4,6-tetra-thiapentalene) has it dimerized structure along the donor stacking direction. and shows semiconducting behavior below room temperature. ESR, static magnetic susceptibility, and optical reflectance of this salt hare been measured to investigate the spin state and the electronic correlation. The ESR signal. has been observed from room temperature to 3 K, and the spin susceptibility shows paramagnetic behavior with a rapid decrease below 10 K. The static magnetic susceptibility is paramagnetic and has an anomaly around 10 K in agreement with the ESR result. The chain axis optical reflectance spectra show clear optical gap in the mid-infrared region. An: attempt is undertaken to analyze the optical spectrum by means of the one-dimensional dimerized Hubbard model, which suggests that the on-site Coulomb repulsion, U, is small and the spin polarization is located at the marginal paramagnetic boundary. These results indicate that this compound is not a band-insulator but the Mott insulator with a small spin gap.
