摘要：

The crystal structure of the title compound, dimethyl-ammonium tetrachlorocobaltate(II). has been determined at four temperatures between 297 and 366 K, in order to investigate possible phase transitions at 313 and 353 K [Kapustianik. Polovinko & Kaluza et at. (1996). Phys. Status Solidi A, 153, 117-122]. We found that there is no significant change either in the hydrogen-bonding network or in the cell parameters, apart from a linear dilatation with temperature. This study reveals that the anomalous variation in electric conductivity and some of the other physical properties of the compound cannot be explained by structural changes.
