A strongly polarized organic conductor

The electrically conducting salt alpha-(BEDT-TTF)2(PO-CON(CH3)CH2SO3) center dot 3H(2)O crystallized in the polar space group, Pna2(1). 2D conducting BEDT-TTF layers and anion layers alternate along the crystallographic c axis. In the crystal, permanent dipoles of all anions point along the c axis, providing a net crystal dipole moment.
