\( \left[\boldsymbol{C r}\left(\boldsymbol{N} \boldsymbol{H}_{3}\right)_{6}\right]\left[\boldsymbol{C r}(\boldsymbol{S C} \boldsymbol{N})_{6}\right] \) and \( \left[\boldsymbol{C r}\left(\boldsymbol{N} \boldsymbol{H}_{3}\right)_{2}(\boldsymbol{S C N})_{4}\right]\left[\boldsymbol{C r}\left(\boldsymbol{N} \boldsymbol{H}_{3}\right)_{4}(\boldsymbol{S C N}\right. \) are the examples of what type of isomerism?

  1. lonisation isomerism
  2. Linkage isomerism
  3. coordination isomerism
  4. Solvate isomerism

Correct answer: coordination isomerism

Solution

These compounds differ by how NH3 and SCN− are split between the complex cation and complex anion. Since the ligands are exchanged between the two coordination entities, this is coordination isomerism.
