M. Yanai et al., ELECTRIC AND MAGNETIC-PROPERTIES OF A NEW CONDUCTING SALT (DMTSA)(2)CL (DMTSA=2,3-DIMETHYL-TETRASELENOANTHRACENE), Synthetic metals, 79(2), 1996, pp. 155-157
A novel charge transfer salt (DMTSA)(2)Cl was synthesized, where DMTSA
is 2,3-dimethyl-tetraselenoanthracene. The salt belongs to a tetragon
al space group, and lattice constants are a = b = 17.5 Angstrom, c = 5
.06 Angstrom. Temperature dependences of the conductivity and of the m
agnetic susceptibility reveal that the system undergoes a metal-insula
tor transition around 240 K. A high-pressure experiment indicates that
this transition does not arise from the one dimensionality of the ele
ctronic structure, such as the Peierls transition.
