Abstract

The dimethyl-, bis(methylthio)-, and ethylenedithio-derivatives of methylenedithio-tetraselenafulvalene and methylenedithio-diselenadithiafulvalene have been synthesized as new electron donors. The formation and electrical conductivities of their radical cation salts are examined.

Keywords

tetraselenafulvalenes - selenium - electron donors - organic conductors - crystal structure
