The title compound [C₆H₉(CH₂)₂NH₃]₂CrO₄ has been prepared as a single crystal by slow evaporation at room temperature. It was characterized by EDX analysis, infrared spectroscopy, UV-visible and thermal analysis TG-DTA. The crystal structure was determined by single crystal X-ray diffraction. This compound crystallizes in the monoclinic system, space group P2₁/c. The cell parameters are: a = 6.475(5) Å, b = 8,173(2) Å, c = 37.010(1) Å. β = 92.94(5)°, V = 1956(1) ų with Z = 4. The asymmetric unit contains one chromate anion and two independent organic cations noted A and B, The structure consists of inorganic layers parallel to (001) plane, separated by organic double layers, The structural cohesion is established by a two-dimensional network of N-H...O hydrogen bonds.
