A Robust (10,3)-a Network Containing Chiral Micropores in the AgI Coordination Polymer of a Bridging Ligand that Provides Three Bidentate Metal-Binding Sites

Framework integrity is retained when water molecules replace the nitromethane molecules in the coordination polymer Ag(hat)ClO4⋅2 CH3NO2 (see picture for structure), which are arranged in a helical fashion within the chiral micropores of the three-dimensional Ag(hat)+n network with a (10,3)-a topology. Remarkably, this is also the case after subsequent displacement of the water by nitromethane molecules. hat=1,4,5,8,9,12-hexaazatriphenylene.
