Varieties of self-assemblies are formed by interactions of discrete molecules or sub-assemblies within an assembly through van der Waals interactions, and various other weak non-covalent interactions such as hydrogen bond, π-π, cation-π, anion-π, C-H···π interactions. Directional properties and hierarchical strengths of weak interactions make avenues to generate different assemblies with novel properties. Inspired by nature emerging concepts of supramolecular building blocks with biological species such as DNA and proteins have been studied. Orderly arranged molecular assemblies guided by directional properties of hydrogen bond helps in function of several natural processes. Intense interest is generated on supramolecular aspects of inorganic complexes to use in bottom-up synthesis procedure to construct assemblies with new material properties. Molecular level understanding of self-assemblies of simple metal complexes requires identifications of sub-assemblies within an assembly to think of new constructions.
