## Symmetry in Square Base Pyramidal Complexes### Question 2Short questions, all-or-nothing. There may be more than one answer per question.#### Diagram Description:The diagram shows a square base pyramidal complex with a nickel center (Ni) coordinated to five cyanide (CN) ligands, labeled as [Ni(CN)5]3-. It features one axial CN ligand and four equatorial CN ligands arranged in a square planar geometry. The terms "axial" and "equatorial" are marked to indicate the positions of the ligands.### Part aFor the square base pyramidal complex \([Ni(CN)_5]^{3-}\) shown above, belonging to the \(C_{4v}\) point group, consider the rotation axes: \(2C_4\) and \(C_2\). If the axial CN ligand was substituted by CO, forming \([Ni(CO)(CN)_4]^{2-}\), maintaining the square pyramidal geometry, which symmetry elements would be retained:i. Both \(C_4\) and \(C_2\).ii. Only the \(C_2\).iii. Only the \(C_4\).iv. None of the above### Part bLooking at the symmetry planes: \(2σ_v\), \(2σ_d\); what symmetry elements would be retained if the CO substitution would occur on an equatorial CN ligand (forming again \([Ni(CO)(CN)_4]^{2-}\) instead)? The dihedral planes in this case are the mirror planes that bisect the square planar bonds.i. All \(σ_v\)ii. All \(σ_d\)iii. At least 1 \(σ_d\)iv. At least 1 \(σ_v\)
