The neutral-ionic transformation in mixed-stack organic charge-transfer (CT)crystals has been analysed within a phenotnenological theory. The theory uses twoparameters: lattice distortion (the stack dimerization) which breaks inversion symmetry and molecular deformation (related to molecular ionicity) which preserves sitesymmetry. A coupling of totally symmetric molecular vibrations with a chargetransfcr between donor and acceptor znolecules allows to introduce the concept ofmolecular compressibility which includes both elastic and electronic contributions.The concept helps to urnderstand discontinuity of the neutral-ionic transformationand can be usefull in 1.he theory of solid state chemis1.ry.
