Recently a new crystal was grown: namely (CH3ΝH3)5Bi2C111 with promis-ing dielectric properties [1]. This compound crystallizes at room temperature inorthorombic symmetry with space group Ρcα21. With increasing temperature crys-tals transform from the ferroelectric phase to the paraelectric phase at aboutTC = 308 K. The phase transition is the second order with a peak of electric per-mittivity 5 x 103 [1]. The authors of Ref. [2] paid attention to similarity of thedielectric properties of this crystal and isomorphic (CH3ΝH3)5Bi2Br11 crystal, forwhich dilatometric anomaly was shown in [3].
