Dielectric properties of [N(CH_{3})_{4}]_{3}Bi_{2}X_{9} (X = Cl, Br) single crystals were measured in the frequency range 1 kHz - 1 MHz in the vicinity of structural phase transitions of first-order type at 152 K (Cl) and 183 K (Br). The pyroelectric effect was observed in [N(CH_{3})_{4}]_{3}Bi_{2}[N(CH_{3})_{4}]_{3}Bi_{2}Cl_{9} at structural phase transition (T_{c} = 152 K) with the ΔP_{s} of the order of 10^{-5} C m^{-2}. Polarized microscope observations show appearance of ferroelectric domain structure in [N(CH_{3})_{4}]_{3}Bi_{2}Br_{9} within the low temperature phase.
