The results of the linear thermal expansion studies on(CH3NH3)5Bi2Br11single crystals in the temperature range 60–340 Kare presented. The thermal anomaly in the vicinity of 77 K is assigned tothe phase transition classified as close to first order type. The pyroelectricmeasurements of (CH3NH3)5Bi2Br11were carried out in the range of45–320 K along thea- andc-axis. The step-like change in the spontaneouspolarization along thea-axis at 77 K indicates a discontinuous character offerroelectric transition.
