Cesium tungsten phosphate oxide, CsP8W8O40, bronze single crystals were grown by chemical vapor transport with KBr as the transporting agent. Electrical resistivity measurements on oriented crystals with ρ{variant}a (RT) = 5.9 × 10-2 Ω cm, ρ{variant}b (RT) = 4.5 × 10-2 Ω cm, and ρ{variant}c (RT) = 5.7 × 10-3 Ω cm indicate quasi-one-dimensional behavior. A broad transition observed at ∼160 K may be attributed to order-disorder transition associated with the Cs+ ions, or a change of the type of conductivity from hopping type (activated) to band type (nonactivated). Qualitative Seebeck measurements of CsP8W8O40 indicate p-type behavior at room temperature and n-type behavior at liquid N2 temperature. A sharp transition seen at ∼24 K might be due to a charge-density wave instability inherent in a quasi-one-dimensional metal. Magnetic susceptibility data indicate Pauli paramagnetic behavior. The anomalies observed in the resistivity do not show up in the magnetic susceptibility.
