TL;DR: The TEM, SEM, and powder XRD studies revealed that whereas L is crystalline, that of the mercury complex is not, perhaps a reason for not being able to obtain single crystals of the complex.
Abstract: Amide linked lower rim 1,3-dibenzimidazole derivative of calix[4]arene, L has been shown to be sensitive and selective to Hg2+ in aqueous acetonitrile solution based on fluorescence spectroscopy, and the stoichiometry of the complexed species has been found to be 1:1. The selectivity of L toward Hg2+ has been shown among 11 M2+ ions, viz., Mn2+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+, Pb2+, Ca2+, and Mg2+ studied, including those of the mercury group and none of these ions impede the recognition of Hg2+ by L. Role of the solvent on the recognition of Hg2+ has been demonstrated. The role of calix[4]arene platform and the benzimidazole moieties in the recognition of Hg2+ by L has been delineated upon performing such studies with five different molecules of relevance as reference molecular systems. The binding cores formed by the receptor L and the reference compounds have been established based on the single crystal XRD structures, and the preferential metal ion binding cores have been discussed. The bind...

TL;DR: The reaction of H-SD (sulfadiazine) with Zn(OAc)2·2H2O in water-ethanol under solvothermal reaction conditions yields crystals of Zn (SD)2 (1) suitable for X-ray analysis as mentioned in this paper.
Abstract: The reaction of H-SD (sulfadiazine) with Zn(OAc)2·2H2O in water–ethanol under solvothermal reaction conditions yields crystals of Zn(SD)2 (1) suitable for X-ray analysis and its 1-D polymeric nature is biologically relevant to the slow release of Zn2+ when applied in topical burn therapy.
