Synthesis, Characterisation and Hirshfeld surface analysis of some Mercury(II) molecular adducts with macrocyclic ligands

Abstract

Fifteen complexes of Hg(II) of the type [HgX2.L1-5] with macrocyclic ligands derived from 9,10-phenanthren-quinone and different aliphatic diamines NH2(CH2)nNH2 (where n = 2 or 3 or 4 or 5 or 6) have been synthesised and characterised by elemental analysis, molar conductance, Hirshfeld analysis, IR and XPS data. An octahedral geometry was established with diamagnetic nature for each molecular adducts. Hirshfeld surface analysis was utilised to characterise the 3D intermolecular interactions on the crystal surface while fingerprint plots were used to illustrate the 2D interactions. Increasing H-H/C-H/O-H/C-C linkages helped to stabilise 9,10-phenanthrene-quinone.
