Two new Hg(II) coordination polymers containing N,N0-Bis-pyridin-3-ylmethylene-naphtalene-
1,5-diamine ligand were synthesized by conventional and sonochemical methods, characterized by
spectroscopic techniques (FT-IR and elemental analysis), and their X-ray crystallographic structures were
determined. The crystal packing and supramolecular features of these coordination polymers were
studied using geometrical analysis and Hirshfeld surface analysis. The crystal structure analysis revealed
that H H contacts, C–H p and C–H X (X = Cl for 1 and X = Br for 2) hydrogen bonding interactions are
strong enough to govern the supramolecular architecture. The BFDH analysis helps us to compare the
predicted morphology to that obtained under ultrasonication. This study may provide further insight into
discovering the role of weak intermolecular interactions in the context of nano-supramolecular assembly.
