Structure determination from powder for brightly emitting copper(I) iodide coordination polymers

Clusters of Copper(I) halides constitute a large family of compounds studied for decades for their photophysical and photochemical properties which are currently at the forefront of coordination chemistry and crystal engineering research. Coordination systems based on CuX show a remarkable structural diversity, which arises from the many possible combinations of coordination numbers available for Copper(I) and the geometries that can be adopted by the halide ions. This variability allows to obtain several different compound by the different stoichiometry combination of CuX and the ligand but at the same time makes the crystal engineering of copper halides particularly difficult.
