The Role of intermolecular Interactions in the Supramolecular Architecture of a Series of Isostructural Group IIB Coordination Complexes

The supramolecular chemistry of metal-containing compounds has attracted intense attention due to not only their fascinating structures,[1]. but also their potential applications in diverse fields such as ion and molecular recognition[2].The ultimate goal of supramolecular chemistry is to understand the inherent complexities of association mechanisms of molecular and ionic building blocks organized through non-covalent intermolecular interactions with prescribed properties and functions [3]. in continuation of our research program aiming at the understanding of the role of non-covalent interactions in the fabrication and self-assembly of metal-containing building blocks a series of coordination compounds, namely[ZnL2I2], [CdL2Br2] and [HgL2I2] where L is 2-(((2-methoxyphenyl)imino)methyl)phenol have been synthesized and characterized using X-ray crystallography and different spectroscopic techniques. The geometrical and Hirshfeld surface analyses and theoretical calculation reveal the importance of π-π stacking interactions as well as hydrogen bonding in governing the crystal packing of these series of isostructural metal-containing compounds. all compounds exhibit infinite 1D ladders in the solid state governed by the formation of H-bonding and π–π stacking interactions in the solid state
