| Abstract: | The monoclinic modification of dipotassium dichromate, β‐K2Cr2O7, has been synthesized in the K2Cr2O7–H2O system. The structure consists of K+ cations and Cr2O72? dimers. In contrast with triclinic α‐K2Cr2O7 Kuz'min, Ilyukhin, Kharitonov & Belov (1969). Krist.Tech. 4 , 441–461], the Cr2O72? groups in β‐K2Cr2O7 have twofold crystallographic symmetry and are parallel to each other. |
