The three step synthesis of 2,3,6,7-Tetrakis(methylthio)naphthalene (T
MTN) 1 is described. The title donor gives a 1: 1 salt with hexafluoma
rsenate anion. The crystal structure consists of a dimerized donor sta
ck, with alternate stacking. The conductivity is activated, room tempe
rature conductivity; almost-equal-to 10(-3).10-4 Scm-1. The susceptibi
lity is quite low, chi(300K)= 7-10(-7) emu/mol, and the ESR linewidth
is DELTAB(pp)(300K)almost-equal-to 5 G. [GRAPHICS]
