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.

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)–copper(II)complexes possessing antibacterial and antifungal activities.

Analysis Note

Contains a small amount of mercurous thiocyanate insoluble in dilute acid.

Disclaimer

For U.S. Customers: Contains mercury; Do not place in trash - dispose according to local, state, or federal laws.
