Question

4) The microanalysis of a compound A is Co 34.47%, C 28.10%, O 37.43%; the compound is neutral, and does not have any signal in the ESR spectrum. What is the formula of the compound? The 13C-NMR spectrum of A shows 2 signals and its single crystal resolved structure reveals that the point group symmetry of A is C2v. When dissolved in an organic solvent A can interconvert into another isomer B which has only 1 signal in the 13C-NMR spectrum and a point group symmetry D4d. Draw the structures of A and B and explain the NMR data.
