A reentrant orthogonal smectic A phase below the tilted smectic C phase is established in a chiral liquid crystalline compound. The temperature evolution of the layer spacing confirms monolayer structure in both smectic A phases, the upper SmA as well as the reentrant SmA phase. The reentrancy of the SmA phase is explained on the basis of the mean field free energy taking into account non-monotoneous temperature dependence of the lowest term coefficient.
