Antimony Compounds as Potential Ferroelectric Materials

Compounds of antimony(III, V) were obtained: {[2,6-(ОMe)2C6H3)3]EtSb}I, [(2,6-OMe)2C6H3]3SbO, [Sb(μ2-O)Cl(DMSO-О)]n, [(2,6-OMe)2C6H3]3Sb(N3)2, (C6H5)3SbBr2, [(C6H5)3Sb(NCO)]2O⋅C4H8O2, being by potential ferroelectrics. Temperature dependences of the permittivity of the compound were studied. According to dielectric measurements, it was established that for the compound [(C6H5)3Sb(NCO)]2O⋅C4H8O2 a phase transition is observed at a temperature of 164°C. The presence of hysteresis on the temperature dependence of ε' indicates a first-order phase transition.
