Dipotassium tetrachromate(VI), K2Cr4O13
Artikel i vetenskaplig tidskrift, 2005

The structure of dipotassium tetrachromium(VI) tridecaoxide, K2Cr4O13, has been determined from single-crystal X-ray data collected at 173(2)K on a racemically twinned crystal with monoclinic Pc space-group symmetry. The structure is composed of discrete [Cr4O13]2- zigzag chains held together by the charge-balancing potassium ions. The conformations adopted by the tetrachromate anion in alkali metal salts and Cr8O21 are different and can be divided into three categories.

crystal structure determination

racemic twin

coordination

X-ray diffraction
