Pseudo-polymorphic Mercury Coordination Polymers: Synthesis, Crystal Structure andHirshfeld Surface Analysis

Three novel mercury (II) coordination polymers were synthesized, incorporating the ditopic ureabasedligand (۴,۴-bu). These coordination polymers, namely {[Hg(۴,۴-bu)Cl۲](DMSO)۳}n (۱), {[Hg(۴,۴-bu)Br۲](DMSO)۳}n (۲), and {[Hg(۴,۴-bu)I۲](DMSO)۴}n (۳), were characterized using infrared analysis, elementalanalysis, thermogravimetric analysis (TGA), and powder X-ray diffraction (PXRD). Single-crystal X-ray diffractionanalysis revealed that all these compounds form ۱D zig-zag chains, which further self-assembled into higherdimensionalstructures through diverse hydrogen-bonding interactions involving the urea functional group andseveral DMSO solvent molecules.
