ABSTRACT
The crystal structure of (H(3)O)(2)Cr(4)O(13) is isotypic with K(2)Cr(4)O(13). The finite tetra-chromate anion in the title structure consists of four vertex-sharing CrO(4) tetra-hedra and exhibits a typical zigzag arrangement. The crystal packing is stabilized by hydrogen bonds between these anions and hydro-nium cations. The two different hydro-nium cations are surrounded by nine O atoms of tetra-chromate anions, with O⋯O distances ranging between 2.866 (8) and 3.282 (7) Å.

No MeSH data available.


Hydrogen bonds between the hydronium ion (O1W) and the surrounding tetrachromate anions. The oxygen atom of the hydronium ion is shown with anisotropic displacement parameters at the 50% probability level. Chromate anions are shown as green-blue tetrahedra. Dashed lines denote O···O contacts between the cation and the anions.
