Useful:

• Canonical SMILES: C(#N)[S-].C(#N)[S-].[Co+2]
• Description: This deep red-violet salt is obtained as the tetrahydrate by crystallization of an aqueous solution of cobalt carbonate in thiocyanic acid. It is very deliquescent and gives a dark blue concentrated solution which turns pink upon dilution. It gives blue solutions in many organic solvents.
• Uses: Cobalt(II) thiocyanate is best known for the cobalt thiocyanate test (or Scott test), which is a proven screening test for the presence of cocaine.
