shares its negative charge approximately equally between sulfur and nitrogen. Thiocyanate can bind metals at either sulfur or nitrogen -- it is an ambidentate ligand. Other factors, e.g. kinetics and solubility, sometimes influence the observed isomer. For example, [Co(NH₃)₅(NCS)]²⁺ is the thermodynamic isomer, but [Co(NH₃)₅(SCN)]²⁺ forms as the kinetic product of the reaction
