    Domains of opposite chirality can exist either in synclinic ferroelectric or in anticlinic antiferroelectric structures in B2 phase of bent-shaped molecules. These domains are separated by π-walls with either right-hended or left-handed rotations of molecular polarizations. In this study, periodic systems of domains of opposite chirality connected by π-walls are discussed. A simple estimation of this periodicity is proposed. Systems of domains and walls create global structures which could have also opposite chirality - so-called superstructural chirality of the system.
