a)The complex have Oh point group symmetry.
b)since the3p orbitals are all pointing directly towards the negative pointcharges of the ligands (that would be on the x,y, and z axis of anoctahedral structure) theoretically the repulsive forces would besimilar to a dz^2 or dx^2-y^2 orbital. So all of the 3p orbitals,each being aligned with an axis would be the same energy level, so?o shouldbe 0 in the crystal field splitting diagram
c and d are given in image.

3.) Consider the arrangement of ligand in a tetrahedral metal complex (MLA), and the resulting crystal field splitting that was discussed in class. What would you expect the crystal field splitting pattern to look like for a cubic complex ML8, which has 8 ligands at the corners of a cube? Draw the orbital splitting diagram with all orbitals labelled. Give your rationale for the pattern. How would you expect the size of the splitting to compare to that for ML4....
4.) Square planar metal complexes (ML) are an extreme case of tetragonal elongation, where the metal-ligands bonds along the z axis of an octahedral complex are stretched until the ligands are completely removed from the metal complex. Using the octahedral crystal field below as a starting point, show how the orbital splitting changes upon elongation of the M-L bonds along the z-axis until the two axial ligands are removed. Label all orbitals and use dashed guidelines to show how individual...

2.) Starting with the octahedral (ML6) crystal field splitting pattern below: A.) Draw the d-orbital splitting for a tetragonally compressed compound (ML6). This is where the ligands along the z-axis are pushed closer to the metal center, and the ligands along the x and y-axis are pulled further from the metal center (10 marks). B.) Continue this trend until the ligands along the x and y axes are completely removed, and show the d-orbital splitting for the resulting linear complex...

1. Consider the following 4-coordinate complexes. For each of these: a. Do you expect the complex to be tetrahedral or square planar? Why? b. Draw an electron-orbital occupancy diagram for the d orbitals. c. If the complex is tetrahedral, calculate an LFSE in units of 4. Note that, for tetrahedral complexes, e orbitals are -3/54 relative to the average d-orbital energy, and t, orbitals are +2/54 relative to the average d-orbital energy. Ni(CO). [Rh(PPh.)

i can't solve this question of coordination chemistry, could someone hlep me please Exercise 1: 1. What kind(s) of interaction between the ligand and the metal ion is(are) considered in the crystal field approach? 2. Give and justify the degeneracy lifting for a tetrahedral complex. Would it be the same for an octahedral complex? 3. Let us consider hexaaquacopper(II) ion. Justify the elongation of two opposite Cu-O bonds (along z for example) compared to the other four Cu-O bonds using...
