Bottom Line: The resulting zigzag chains extend along the a-axis direction and are arranged in a distorted hexagonal rod packing.The p-anisidinium cations and the water mol-ecules are located in the voids of the anionic sublattice.The cations are linked to each other through N-H⋯O hydrogen bonds with the water mol-ecules, and also through weaker N-H⋯I inter-actions to the anionic inorganic layers.

ABSTRACT
A new organic-inorganic hybrid material, {(C7H10NO)[BiI4]·2H2O} n , has been synthesized by slow evaporation of an aqueous solution at room temperature. The anionic sublattice of the crystal is built up by [BiI6] octa-hedra sharing edges. The resulting zigzag chains extend along the a-axis direction and are arranged in a distorted hexagonal rod packing. The p-anisidinium cations and the water mol-ecules are located in the voids of the anionic sublattice. The cations are linked to each other through N-H⋯O hydrogen bonds with the water mol-ecules, and also through weaker N-H⋯I inter-actions to the anionic inorganic layers.

Mentions: The role of the water mol­ecules is crucial in the crystal cohesion. In fact, OW1 is engaged in three hydrogen bonds to one organic cation, one [BiI6] octa­hedra and one water mol­ecule via OW1⋯HBi—Ni, OW1—HW1A⋯I3 and OW1⋯HW2Bii—OW2ii, respectively, as shown in Fig. 5 ▸ [symmetry codes: (i)  − x,  + y,  − z; (ii) x + 1, y, z). The second water mol­ecule OW2 is linked to OW1 by OW2—HW2B⋯OW1(−1 + x, y, z) and to the p-anisidinium cation by N—HC⋯OW2 hydrogen bonds as shown in Fig. 6 ▸. The role of this water mol­ecule can be seen better in Fig. 7 ▸ where mol­ecular stacking along the b axis is observed, leaving an empty inter­layer space where OW2 mol­ecules are located, ensuring a strong link between organic and inorganic sheets.
