Zeolite-like copper iodide framework with new 6(6) topology

We have described an unprecedented three-dimensional zeolite-like copper iodide constructed from Cu4I4(DABCO)4 (DABCO = 1,4-diazabicyclo[2.2.2]octane) supertetrahedron units. This compound forms a four-connected network with new 6(6) topology. Its structure reveals one-dimensional channels along the [001] direction, and the framework displays interesting self-penetration. The title compound shows photoluminescence at room temperature in the solid state.
