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.

Summary
Previous X-ray structural studies showed that halogenidobismuthate(III) complexes may contain an array of variously self-organized halobismuthate anions since different polynuclear species can be formed through oligomerization by halide bridging (Bowmaker et al, 1998; Benetollo et al, 1998; Alonzo et al, 1999). The coordination sphere of bismuth appears to be dominated by an hexacoordination tendency with polybismuthate species arising from corner-, edge- or face-sharing [BiX6] distorted octahedra. If the anionic sublattice dimensionality is clearly determined by the counter-cations, the effects of their most evident properties such as charge, size and shape are not predictable. In an effort to increase the size of the [BiX6] octahedra, iodine was used in the chemical synthesis
