Tetrathiafulvalene revisited

A. S. Batsanov

Abstract: Monoclinic ( [alpha] ) tetrathiafulvalene [systematic name: 2-(1,3-dithiol-2-ylidene)-1,3-dithiole], C₆H₄S₄, undergoes a reversible second-order phase transition at ca 190 K through a displacive modulation with doubling of the a parameter. The low-temperature phase ( [gamma] ) contains two crystallographically non-equivalent (but centrosymmetric) molecules of very similar geometry.

Formula: C₆H₄S₄, C₆H₄S₄ and C₆H₄S₄
