摘要：

A novel selenium-containing bis-fused tetrathiafulvalene donor, TSM-TTP (2,5-bis[4,5-bis(methylseleno)-1,3-dithiol-2-ylidene]-1,3,4,6-tetrathiapentalene) forms a 3 : 5 triiodide salt, (TSM-TTP)(I-3)(5/3). This salt has uniform one-dimensional columns of the donors, and is isostructural to the corresponding complex of the sulfur analog. This compound shows a high electrical conductivity, 200 S cm(-1) at room temperature, and undergoes a metal-insulator transition around 20 K. Another insulating (sigma(rt) = 0.03 S cm(-1)) phase with trimerized columns is also obtained.
