Crystal structure of trans-cyclo­hexane-1,2-di­ammonium chromate(VI) from synchrotron X-ray diffraction data

The structure of the title hybrid compound, (C(6)H(16)N(2))[CrO(4)], has been determined from synchrotron data. The organic cation adopts a chair conformation. The inorganic CrO(4) (2−) anion is slightly distorted owing to its involvement in N—H⋯O hydrogen-bonding inter­actions with neighbouring trans-cyclo­hexane-1,2-di­ammonium cations, whereby the two Cr—O bonds to the O atoms acting as acceptor atoms for two hydrogen bonds are slightly longer than the other two Cr—O bonds for which only one acceptor inter­action per O atom is observed. In the crystal, cations and anions are packed into layers parallel to (001), held together through the aforementioned N—H⋯O hydrogen bonds.
