(A) Triangular motif sustained by bifurcated I···O and I···π XBs in the packing of TIPB. (B) Honeycomb-like network in TIPB. Hexagonal channels are filled by chloroform molecules (in green). (C) Two-dimensional array (sql) of tin tetrakis(iodophenyl)porphyrin with nicotinic acid (POR1) aligned parallel to the ac plane of the crystal. (D) Square-grid-type network in the crystal of tetrakis(iodophenyl)porphyrin assembled with 1-hydroxybenzotriazole (POR2). Every porphyrin unit is involved in eight XB contacts. (E) View parallel to the crystal ab plane of bis(iodoaryl)dipyridylporphyrin free base (POR3). (F) Representative section of the halogen-bonded layer in POR4, viewed within the crystal ac plane. XBs are dotted lines. Panels A and B reprinted with permission from ref (746). Copyright 2008 Royal Society of Chemistry. Panels C and D reprinted with permission from ref (748).
