See Answer →Six-coordinate d9 complexes of copper (+2) show pronounced tetragonal distortions. High-spin d4 (e.g., Cr2+ and Mn3+ and low-spin d7 six-coordinate complexes (e.g. Co2+ and Ni3+) may show a similar distortion, but complexes of these ions are less common, and the distortions are less pronounced than those in copper (+2). Why?
