A two‐dimensional silver–iodide organic network constructed from a unique [Ag6I6] hexagonal prism‐based one‐dimensional column motif

A novel two-dimensional coordination polymer, poly[[μ2-1,3-bis­(2-methyl-1H-imidazol-1-yl)propane]di-μ4-iodido-di-μ3-iodido-silver(I)], [Ag4I4(C11H16N4)]n, (I), has been synthesized by solvothermal reaction of AgNO3, KI and 1,3-bis­(2-methyl-1H-imidazol-1-yl)propane (bmimp). In (I), the two unique AgI cations have AgNI3 and AgI4 four-coordinated tetra­hedral geometries. The bmimp ligand has imposed twofold symmetry. The AgI cations and iodide anions form a unique one-dimensional polymeric column motif incorporating [Ag6I6] hexa­gonal prisms, which are then connected by bmimp ligands to form two-dimensional organic–inorganic layers. The layers are arranged in parallel in an ABAB fashion and are packed into the resultant three-dimensional supra­molecular framework by van der Waals inter­actions.
