Abstract
The title compound crystallizes in the monoclinic space group P21/c, with cell parameters a = 6.493(5), b = 11.560(6), c = 13.384(8)Å, β = 118.19(5)°, V = 885.4(10)Å3 and Z = 4. Its crystal structure was determined and refined to a final R = 0.073 (Rw = 0.209) for 2534 independent reflections. In the crystal, the 3-ammoniomethyl pyridinium cations are anchored between clusters formed by sulfate anions and water molecules via N-H…O hydrogen bonds to build an infinite layer parallel to the bc plane at x = 1/2. Crystal cohesion and stability are supported by electrostatic and π-π interactions which, together with hydrogen bonds, build up a three-dimensional network.
