Abstract
Two new co-crystals, tetra-iodo-ethyl-ene-phenanthridine (1/2), 0.5C2I4·C13H9N (1) and tetra-iodo-ethyl-ene-benzo[f]quinoline (1/2), 0.5C2I4·C13H9N (2), were obtained from tetra-iodo-ethyl-ene and aza-phenanthrenes, and characterized by IR and fluorescence spectroscopy, elemental analysis and X-ray crystallography. In the crystal structures, C-I⋯π and C-I⋯N halogen bonds link the independent mol-ecules into one-dimensional chains and two-dimensional networks with subloops. In addition, the planar aza-phenanthrenes lend themselves to π-π stacking and C-H⋯π inter-actions, leading to a diversity of supra-molecular three-dimensional structural motifs being formed by these inter-actions. Luminescence studies show that co-crystals 1 and 2 exhibit distinctly different luminescence properties in the solid state at room temperature.
