Electric and magnetic properties of a new conducting salt (DMTSA)2Cl (DMTSA = 2,3-dimethyl-tetraselenoanthracene)
1996
Abstract A novel charge transfer salt (DMTSA) 2 Cl was synthesized, where DMTSA is 2,3-dimethyl-tetraselenoanthracene. The salt belongs to a tetragonal space group, and lattice constants are a = b = 17.5 A, c = 5.06 A. Temperature dependences of the conductivity and of the magnetic susceptibility reveal that the system undergoes a metal-insulator transition around 240 K. A high-pressure experiment indicates that this transition does not arise from the one dimensionality of the electronic structure, such as the Peierls transition.
