  Abstract:  X-ray diffraction and dielectric permitivity data performed on Pb2Mg1-xCoxWO6 solid solutions with 0  x  0.3 are reported. By partial cobalt substitution for magnesium the diffraction patterns are similar to that of Pb2MgWO6 compound with a small increase of lattice parameters, which is probable due to the difference in the ionic radii of Mg2+ and Co2+. Dielectric anomaly at Tc (38oC) related to the antiferroelectric transition in Pb2MgWO6 is affected by cobalt substitution for magnesium by Tc decreases.
