Some ferroelectric and crystallographical properties of the compound Ba2Bi4Ti&0» are presented. The compound represents a new structure with the unit cell consisting of one Bi2022+ layer and five perovskite layers. From -196' to +580'C, a maximum in the real part of the dielectric constant was observed at 329'C. No thermal hysteresis was observed within the precision of~2'C, A remanent polarization of 2X10 ' coul/cm' and a coercive 6eld of 10 kv/cm were observed at room temperature.
