Structural and luminescent properties of co-crystals of tetra-iodo-ethyl-ene with two aza-phenanthrenes.

Two new co-crystals, tetra-iodo-ethyl-ene-phenanthridine (1/2), 0.5CI·CHN () and tetra-iodo-ethyl-ene-benzo[]quinoline (1/2), 0.5CI·CHN (), were obtained from tetra-iodo-ethyl-ene and aza-phenanthrenes, and characterized by IR and fluorescence spectroscopy, elemental analysis and X-ray crystallography.
