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 principal building blocks of the title compound are octahedral iodidobismuthate [BiI6] units, p-anisidinium cations and two water mol­ecules (Fig. 1 ▸). The anionic sublattice of the crystal is built of one-dimensional zigzag chains extending along the a-axis direction and composed of [BiI6] octa­hedra sharing edges as shown in Fig. 2 ▸. The one-dimensional secondary building unit (SBU) topology observed in the described structure is one of the most common and stable ones (Billing & Lemmerer, 2006 ▸) in bis­muth halide hybrids. The shortest Bi—Bi distance [4.590 (1) Å] observed is in agreement with homologous structures having the same one-dimensional topology. The octa­hedral bis­muth coordination is almost regular, proving the stereochemical inactivity of the Bi3+ 6s2 electron lone pair. Furthermore, among the six octa­hedral vertices, two are monocoordinated with short bond lengths (I2 and I3), while the four others (I4, I1 and symmetry-related atoms) are bicoordinated exhibiting long bond lengths (Table 1 ▸).
