3c) Determine the valence electron count of the complex shown below. Use both counting models andcompare your results. Assume that the Re-N-O bonding angle is 180°.ON!...ReORPPh3Ph3d) The nitrosyl cation is notorious for its ability to function as a non-innocent ligand. This means thatcoordinated NO* can affect the oxidation state of the metal to which it is bound. If the central atom M(1) can adopt more than one stable oxidation state and (2) if the metal is not too electronegative, theNO* can withdraw two electrons from M. Does this redox process alter the geometry of the originallylinear M-N-O bond and the electron count of the nitrosyl ligand? If yes, describe the changes and themodifications that have to be made when determining the valence electron count.

1. The molecule listed to the left was originally MX6 where the symmetry was On. After reduction of the metal center the coordination environment changed and the ligands along the Z-axis elongated(hint: this means that the extent of overlap of orbitals that interact with the z-axis point charges would be lesser than the On molecule). Draw the crystal field splitting of both the On symmetry molecule as well as elongated z-axis molecule with symmetry labels.
