Micro/nanoscale spherical HgS has been prepared by reaction of Na2[Hg(HL)2(H2O)2]; 1:2 (M:L) chelate complex with alkaline solution of thiourea in aqueous solution phase. The metal chelate complex was prepared by reaction of Hg(II) ions with 2-hydroxy-1-(1-hydroxy-2-naphthylazo)-6-nitronaphthalene-4-sulphonic acid sodium salt; eriochrome black T (EBT, NaH2L) in alkaline medium. The chelate complex precursor thus prepared was characterized by various physico-chemical and spectral techniques for structure determination. The spherical HgS material was characterized by scanning electron microscopy and energy dispersive X-ray analysis to determine morphology and chemical composition. The optical property was determined by UV-Vis spectrum. A possible formation mechanism has also been discussed in this article.
