It is shown by extending the Landau theory of freezing that a tendency to form multicontinuous complex structures is possessed by simple systems consisting of rigid rodlike particles. The excellent stability of the Gyroid phase, which is most widely observed in nature, is naturally explained. An exotic structure found in thermotropic liquid crystals can be further regarded as an example.
