The design and development of crystal structure is of immense significance in the realm of supramolecular chemistry. Each crystal is unique of its kind and distinguishes the different arrangement of atoms. However the assembly of these atoms is controlled by its geometry and chemical properties. This kind of structural diversity is widely observed in coordination polymers. In structural arrangement, building blocks play a major role towards architecting the different dimensionalities and accordingly such arrangements possess diverse applicability. Currently various architectures are developed with a wide variation in the building blocks. All the elements existing within the crystal structure works in union by supramolecular non-covalent interactions. The overall stability and diversity in the architecture widely depends on these weak non-covalent interactions which finally lead to different physical properties. Among the weak non-covalent interactions, hydrogen bonding, π-π interactions, Vander Waals attraction are implicitly predominating in developing individual architecture. The spatial orientation of the individual atoms or groups is significant for the development of weak interaction within the structure. The chemical environment and spatial arrangement of the building blocks also govern the distribution of the atoms or groups in the constructional arrangement. Binding arrangement between the building blocks define the diverse dimensionality or different nets of the coordination polymer. Sometimes the development of varying structure depends on the factors including growing environment like pH, solvent, counter ion of the coordination polymer etc. An in-depth introduction of the various building blocks and its importance in construction of different architecture has been discussed in this review. But the primary focus of the present review is to establish and emphasize the role of weak interactions towards architecting different coordination polymer. Our aim is to provide an obvious idea about the correlation between weak non-covalent interaction inside the architecture and the different structural diversity of coordination polymer.
