Black crystals of the bismuth subchloride Bi7Cl10 were obtained by slow cooling of stoichiometric mixtures of Bi und BiCl 3 from 500C to ambient temperature. By means of thermal analyses the phase diagram Bi/BiCl3 was specified. Bi7Cl 10 decomposes peritectoidally into Bi6Cl7 and BiCl3 at 190 ± 5C. The phase barogram of the binary system was determined by total pressure measurements in the membrane zero-manometer. From the pressure functions of the bismuth chlorides as well as from measurements of the molar heat of Bi6Cl7 the thermodynamic standard data were derived: DeltaHB(Bi 6Cl7, 298) = -895 ± 5 kJ·mol-1; S(Bi6Cl7, 298) = 620 ± 10 J·mol -1 K-1; DeltaHB(Bi7Cl 10, 298) = -1310 ± 10 kJ·mol-1; S(Bi7Cl10, 298) = 730 ± 20 J·mol -1 K-1. Using these data, thermodynamic modelling of the solid-gas-equilibria were carried out in order to optimize the synthesis of Bi7Cl10. The phase-pure vapour deposition of Bi 7Cl10 is impossible due to the condensation of the dominating gas-species in the stability range of the compound. X-ray diffraction on single-crystals at room temperature revealed that Bi7Cl 10 crystallizes with the tetragonal space group I 41/a c d and the lattice parameters a = 28.235(3) and c = 39.950(4) A (Z = 64). In the crystal structure, polycations Bi95+ with the shape of tri-capped trigonal prisms are embedded in a chloro-bismuthate(III) framework ?3[Bi5Cl205-].
