Vedclass · Answer

(A) The given complex is $Hg[Co(CNS)_4]$.In this complex,the cation is $Hg^{2+}$ and the anion is $[Co(CNS)_4]^{2-}$.For the anion $[Co(CNS)_4]^{2-}$,the ligand is $CNS^-$,which is thiocyanate. Since it is bonded through the sulfur atom,it is named as thiocyanato-$S$.There are $4$ such ligands,so the prefix is 'tetra'.The central metal atom is Cobalt,and since the complex ion is anionic,it is named as 'cobaltate'.The oxidation state of $Co$ is calculated as: $x + 4(-1) = -2$,which gives $x = +2$.Thus,the name is Mercury tetrathiocyanato-$S$-cobaltate$(II)$.
