Propane-1,2-di-ammonium chromate(VI).
Résumé
In the title mol-ecular salt, (C3H12N2)[CrO4], each chromate anion accepts six N-H⋯O and C-H⋯O hydrogen bonds from nearby propane-1,2-di-ammonium cations. Three of the four O atoms of the chromate anion accept these bonds; the remaining Cr-O bond length is notably shorter than the others. In the crystal, the anions and cations stack in layers lying parallel to (100): the hydrogen-bonding pattern leads to a three-dimensional network.
