“…Panda and Banerjee established the role of π···π interactions in conducting property of 2D layered In(III)-isophthalate CP . Akhtaruzzaman et al have shown that with increase in interchain π···π interactions, the conductivity increases by using two different 1D CPs ([Zn( cis -1,4-chdc)(4-phpy)]n and [Zn( cis -1,4-chdc)(py)]n, (1,4-H2chdc = 1,4-cyclohexanedicarboxylicacid, 4-phpy = 4 phenyl pyridine, and py = pyridine) . The former compound shows superior conductivity than later one, and the authors demonstrated that this 1D coordination chains are assembled through π···π interactions.…”

A paddle-wheel-based multifunctional 1D coordination polymer (CP) {[Cu 2 (4-Cl-Bz) 4 (4,4′-bipy)](DMF) 2 } n (where 4-Cl-BzH = 4-chlorobenzoic acid, 4,4′-bipy = 4,4′-bipyridine, and DMF = dimethylformamide), (complex 1) have been synthesized via the solvothermal method and characterized by single-crystal X-ray diffraction analysis along with other spectroscopic studies. Structural analysis shows that 1 crystallizes in the tetragonal P4 /ncc space group and 1D coordination chains are formed by connecting [Cu 2 (4-Cl-Bz) 4 ] paddle wheel units using 4,4′-bipy moieties along the crystallographic c axis. These 1D coordination chains are assembled to each other through weak π•••π interactions to form interpenetrated 3D supramolecular structure, forming channels along the [1 1 0] and [−1 1 0] direction hosting DMF molecules. Hirshfeld surface analysis and corresponding 2D fingerprint plots indicate that π•••π interaction is the major interaction among the coordination chains. Thermal analysis shows that guest DMF molecules are released within the temperature range of 70−150 °C and powder X-ray diffraction (PXRD) analysis reveals the quenching of the void space after removal of the solvent molecules. The desolvated framework selectively adsorbs CO 2 over N 2 . The magneto-luminescent behavior of the framework has also been studied. This πinduced 3D supramolecular complex shows semiconducting behavior and conductivity increases upon desolvation.

“…5. For the monodentate terminal ligands, pyridine derivatives are the most popular ligands for constructing 0D 58 and 1D 59 CPs with 1,2- or 1,4-CHDC, which can be considered as two-connected linkers. Interestingly, Lin et al showed that the 1e,4a-CHDC ligands bridge the Cd 2+ cations to form trinuclear cluster-based chains which are further linked by 1e,4e-CHDC ligands into a 2D network (Fig.…”

“…In the advancement of modern science, supramolecular chemistry plays a crucial role as it contributes actively in the area of synthetic materials. Over the years, hydrogen bonding and π···π stacking interactions have remained the most familiar supramolecular forces and play crucial roles in many chemical and biological processes. − The existence of halogen-related interactions in organic crystal engineering is also well-established. However, their associations within metal coordination networks are relatively less explored. , …”

Halogen•••halogen interactions have been a matter of debate and interest over the past few decades and still continue to be one of the most fascinating research areas in recent times as these interactions are very useful for designing elements in crystal engineering. In crystal engineering strategies, for designing molecular crystals of varying dimensionality, halogen•••halogen interactions among molecular building blocks affect the molecular assembly and crystal packing. However, most of the studies focus on the organic crystal engineering and explore very little of the metal-containing supramolecular assembly. In this perspective, we exclusively highlight the impact of halogen•••halogen interactions in the structural architectures and applications of coordination polymers (CPs)/metal−organic frameworks (MOFs). Again, these interactions also play a significant role in controlling the structure−property relationships of CPs. Therefore, careful efforts have been dedicated to understand the way that they influence solid-state molecular properties, such as gas sorption, sensing, conductivity, vapochromism, magnetism, and mechanical plasticity etc.
