An investigation is made of the thermopower in the three available directions of crystals of TEA(TCNQ) 2 and on a moulding pellet at temperatures between 100 and 300 °K. The thermopower is found to be highly anisotropic with an anomalous sign for one direction; it is negative in the directions of highest and lowest electrical conductivity but positive in the direction of intermediate conductivity.
