Abstract
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.
