Crystals of bis(pyridine-3-carboxylato)[tetrakis(4-iodophenyl)porphyrinato]tin(IV) dimethylformamide sesquisolvate, [Sn(C44H24I4N4)(C6H4NO2)2]·1.5C3H7NO, (I), and bis(pyrimidine-5-carboxylato)[tetrakis(4-iodophenyl)porphyrinato]tin(IV) dimethylformamide sesquisolvate, [Sn(C44H24I4N4)(C5H3N2O2)2]·1.5C3H7NO, (II), exhibit interporphyrin iodine–iodine halogen bonds, which direct the supramolecular assembly of the porphyrin entities into halogen-bonded layers. Each molecule interacts with its four nearest neighbours within the layerviaeight I...I interactions at approximately 3.8 and 4.0 Å. The two structures are isomorphous and isometric, with the metalloporphyrin complexes located on centres of crystallographic inversion.

The asymmetric unit of the title co-crystalline adduct, 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane (TATD)–4-iodophenol (1/2), C8H16N4·2C6H5IO, comprises a half molecule of the aminal cage polyamine plus a 4-iodophenol molecule. A twofold rotation axis generates the other half of the adduct. The components are linked by two intermolecular O—H...N hydrogen bonds. The adducts are further linked into a three-dimensional framework structure by a combination of N...I halogen bonds and weak non-conventional C—H...O and C—H...I hydrogen bonds.

The supramolecular assembly of halogenated and hydroxyl hydrazones derived from two well known pharmaceuticals, isoniazid (IsX, where X = I, Br, OH) and hydralazine (HyX, where X = I, Br, OH), was studied by X-ray crystallography and theoretical methods. Crystal packing of IsI and HyI shows weak I...N and I...π halogen bonds, whereas the hydrogen bonds are dominant in the brominated scaffolds IsBr and HyBr. Although the calculated I...N interaction strength appears almost three times weaker than the O—H...N contacts in the isoniazid-based hydrazones, the higher directionality of the halogen bonds induces a linear and planar architecture of self-complementary tectons, observed only with the help of a bridging water molecule in the case of IsOH. Finally, the X-ray structure of HyOH is characterized by an unexpected linear arrangement of clathrated dichloromethane molecules bound through type I and II halogen bonds. This rare phenomenon, observed in less than ten structures, was studied by coupled cluster-based energy decomposition.

Stoichiometric Ratios

The isomeric compounds, 4-bromo-2-chloro benzoic acid (4Br) and 2-bromo-4-chlorobenzoic acid (2Br), crystallize in entirely different space groups, P21/n and P1̄ respectively. Both structures are stabilized by a strong O–H⋯O hydrogen bonds generating a carboxylic acid dimer along with an unusual triangular halogen bonded motif in the former and a well-defined halogen bond in the latter. Charge density analysis establishes the nature of halogen bonds by bringing out significant changes in the packing features of the two structures as well as the quantification of the interaction energies involved in the formation of the motifs. Cocrystallization efforts lead to the formation of solid solutions of varied stoichiometric ratios among the two entirely different crystalline forms, a feature which is observed for the first time, and depends on the nature of the halogen bonds. Despite the significant variations in the charge density distribution in intermolecular space, the triangular motif, with two type II Br⋯Cl and Cl⋯Br and one type I Br⋯Br contact in the structure of 4Br dictates the packing preferences in the solid solution as established by accurate single crystal diffraction studies supported by cognate powder diffraction analysis (PXRD) and differential scanning calorimetric (DSC) studies. A systematic study of the solid solution by varying the stoichiometric ratios establishes the hierarchy in halogen bonded motifs and consequently its directional influence to form the resultant supramolecular assembly.
