The formation of a halogen-bonded zigzag molecular network based upon 1,2-diiodoperchlorobenzene and the head-to-tail photoproduct rctt −1,3-bis(pyridin-4-yl)-2,4-diphenylcyclobutane is reported. The co-crystal is sustained by I
N halogen bonds where the photoproduct acts as a linear linker while the donor behaves as a bent two-connected node within the zigzag chain.

In the title compound, two imidazolyl groups are separated by a zigzag –CH=N—N=CH– linkage. Each molecule forms four N—H
N hydrogen bonds with two neighbouring molecules to constitute a one-dimensional ladder-like structure along the a axis.

In the title crystal, molecules are linked by N—H
O hydrogen bonds, forming ribbons parallel to (020) in zigzag C(7) chains along the a axis. These ribbons are connected via C—H
π interactions, forming a three-dimensional network.

In the title compound, each HgII ion is coordinated by two pyridine N atoms from two symmetry-related unsymmetrical dipyridyl ligands and two chloride anions in a highly distorted tetrahedral geometry. Each unsymmetrical dipyridyl ligand links two HgII ions into polymeric zigzag chains. In the crystal, the chains are linked into a three-dimensional supramolecular network by intermolecular N/C—H
Cl hydrogen bonds and weak C—H
π interactions. Weak C—Cl
π interactions and Cl
Cl contacts between the network and the solvent chloroform molecules are also observed.

The reaction of HgII with the bridging ligand bis(pyridin-3-ylmethyl)sulfane afforded a one-dimensional zigzag chain polymeric structure, with the charge balanced by two coordinated chloride anions. C—H
Cl hydrogen bonds and Hg—Cl
π interactions, together with C—H
π hydrogen bonds, stabilize the crystal structure.
