Abstract Large purple-brown crystals of two reduced bismuth molybdenum oxides have been grown from the MoO3–Bi2O3 system by electrolytic reduction of the molten salts. The unit cell parameters and the compositions have been determined by X-ray diffraction and XPS microprobe analysis, respectively. The empirical formulae were refined to Bi0.25MoO3.1 and Bi0.21MoO3.2. Transport measurements (the resistivity and the thermoelectric power) showed that both crystals are semiconductors with p-type carriers, and the thermally activated energy gaps are respectively about 0.296 eV and 0.30 eV. The EPR spectra, the XPS core-level spectra and possible structural features were also considered.
