Abstract
Single crystals of (PO2)(4)(WO3)(2), (m = 13) have been studied by x-r ay diffuse scattering and transport (resistivity, Hall effect and ther mopower) measurements. Three instabilities are found at T-c0 = 510K, T -c2 = 550K and T-c2 = 160K with modulations of wavevector q(0) = (0.5, 0,0), q(1) = (0.053,0.016,?) and q(2) = (0.178,0.145,?). The q(1) an q (2) instabilities are attributed to charge density waves and the q(0) one to an antiferroelectric distortion.
