A novel supramolecular assembly [Hg6As4](AgCl3)2 has been prepared and its structure determined. It crystallizes in the monoclinic system, space group I2/a (no. 15), with the unit-cell dimensions a = 14.690(1), b = 9.1851(7), c = 20.285(1) Å, β = 93.17(1)°, and Z = 4. The crystal structure comprises a three-dimensional cationic host framework, [Hg6As4]4+, built of mercury and arsenic atoms and one-dimensional ∞1(AgCl3)2− guest anions built of corner-sharing [AgCl4] tetrahedra. The title compound is the first example of a perfectly ordered supramolecular architecture having an infinite chain anion as a guest moiety embedded into a mercury−pnicogen cationic framework.
