Abstract

In the crystal structure of the title compound, C29H8F16I4O4, short I⋯I and I⋯F contacts, which can be understood as halogen bonds (XBs), represent the strongest inter-molecular inter-actions, consistent with the presence of I and F atoms, and the absence of H atoms, at the periphery of the mol-ecule. In addition, π-π stacking inter-actions between tetra-fluoro-iodo-phenyl (TFIP) groups and five short F⋯F inter-actions are present.
