Question
With the help of suitable examples and structures, explain why some of the 16-electron organometallic complexes are stable. For a dⁿ metal ion which form will be more stable, 16-electron square planar complex (d⁸ and 8 ligand electrons) or a 18-electron complex (d⁸ and 10 ligand electrons)? Justify your answer.
Answer :
Word Count : 241
Some organometallic complexes deviate from the 18-electron rule and exhibit stability with only 16 electrons. This is especially common in transition metal complexes with d⁸ configuration, such as those of Ni(II), Pd(II), and Pt(II). The reason lies in the preferred geometry and electronic arrangement.
