Can polar molecular crystals really exist? We intend to elaborate a fundamental answer to this question. Here a new basic thesis is presented to investigate this phenomenon by (i) vapour growth and (ii) computational methods.Simulations show a bi-polar state in the sense that along one direction of the polar axis, growth leads to a full reversal of dipoles. It is proposed that the demand for dipole reversal is effecting kinetic hindrance for one direction of the polar axis.
