| Application: | Mercury(II) thiocyanate can be employed as a reactant for the synthesis of: • Polymeric mercury(II) coordination complexes with various derivatives of 4,4′-bipyridine ligands via the branched tube method. • Manganese mercury thiocyanate (MMTC), an organometallic optical single-crystal. • Heterotrinuclear copper(II)–mercury(II)–co |
| General description: | Mercury(II) thiocyanate is the coordination complex of Hg2+ and the thiocyanate ion(SCN-). It is primary used as catalyst for the addition of thiocyanic acid (HSCN) across the triple bond of a variety of alkynes and as a precursor to synthesize other thiocyanate complexes. Within analytical chemistry, it is also used for the colorimetric determination of chloride ions in water. |
