The physical properties and the phase transitions of a smectic liquid crystal material built from achiral bent-core molecules are investigated by electro-optics, polarizing microscopy, birefringence, and spontaneous polarization. This material is shown to exhibit a number of orthogonal and tilted smectic phases. The observation of an anomalous phase transition on cooling from a tilted to orthogonal antiferroelectric smectic phase at lower temperatures is made, and a proof of the evidence is presented. The importance of the biaxial anchoring term in the free energy is modeled and discussed.
