Effect of spacer functional group on the coordination geometry and molecular conformation

چکیده مقاله

In this study, three Hg(II) iodide complexes of N-(naphthalen-1-yl)nicotinamide (L^amide), [HgI₂(L^amide)]_n, 1, N-(pyridin-3-yl)-1-naphthamide (L^{reverse amide}), [HgI₂(L^{reverse amide})], 2 and N-(naphthalen-1-yl)nicotinate (L^ester), [HgI₂(L^ester)₂], 3 have been synthesized and characterized. Structural analysis clearly shows that variance in the spacer functional group has a major impact on density, conformational preference, coordination environment and geometric modes. Furthermore, inter- and intramolecular interactions in crystal packing also influence the defining parameters of conformation, leading to better aromatic-involved interactions both energetically and geometrically. © 2024 Elsevier B.V.
