Propane-1,2-diammonium chromate(VI)

Abstract

In the title molecular salt, (C3H12N2)[CrO4], each chromate anion accepts six N—H...O and C—H...O hydrogen bonds from nearby propane-1,2-diammonium 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.
