What Is The Structure Of Silver Thiocyanate?

Silver thiocyanate has a chemical formula of AgSCN and its structure consists of a silver ion (Ag+) cation bonded to a thiocyanate anion (SCN-).

The thiocyanate anion is composed of a sulfur atom (S) bonded to a carbon atom (C), which in turn is triple-bonded to a nitrogen atom (N). This linear arrangement forms a negatively charged ion due to the presence of an extra electron.

The silver ion has a +1 charge and is coordinated by two nitrogen atoms from the thiocyanate anion, as well as by four neighboring sulfur atoms in a tetrahedral arrangement. The resulting complex ion, Ag(NCS)4-, is distorted tetrahedral with a slightly elongated Ag-S bond length.

Overall, the structure of silver thiocyanate can be described as a 3D arrangement of silver ions and thiocyanate anions held together by ionic bonds.
