Аннотация

The pressure of saturated and unsaturated bromine vapor over solid Bi(III) polybromides (PyH)₃[Bi₂Br₉(Br₂)] and (N-MePy)₃[Bi₂Br₉(Br₂)], where Py is pyridinium, N-MePy is N-methil pyridinium, has been measured for the first time in a wide temperature range using a static method with glass membrane-gauge manometers. As a result of this study the thermal stabilities of investigated complexes were established, the temperature dependences of bromine vapor pressure were obtained, the thermodynamic characteristics of bromine evaporation processes (Δ_prH°_T, Δ_prS°_T) were calculated and a new possibility for the synthesis of polybromides was proposed.
