STRUCTURAL AND ELECTROSTATIC MODULATION BY HYDROGEN-BONDS UPON THE CONDUCTION COLUMN OF NI(DMIT)2 COMPLEX

In order to discuss the effect of dynamic modulation caused by hydrogen-bonded system on the conduction property, two Ni(dmit)2 salts were prepared. In morpholinium salts a remarkable structural modulation was observed on the hydrogen-bonded Ni(dmit)2 molecules. In the crystal of hydrated lithium salts, the hydrogen-bonded cation system is incorporated in a cylindrical channel constructed by corrugatedly stacked Ni(dmit)2 columns, and a distinct hysteresis was observed on the temperature dependence of conductivity. © 1992, Taylor & Francis Group, LLC.
