The thiocyanate ion, SCN^-, can form bonds to metals through either S or N (see Problem 5.23 ). What is the likelihood of cyanide, CN^-, forming bonds to metals through N as well as C?

Reference of problem 5.23

Thiocyanate and cyanate ions both bond to H⁺ through the nitrogen atoms (HNCS and HNCO), whereas SCN^- forms bonds with metal ions through either nitrogen or sulfur, depending on the rest of the molecule. What does this suggest about the relative importance of S and N orbitals in the MOs of SCN^-? (Hint: See the discussion of CO₂ bonding in Section 5.4.2 .)
