inorganic chem. pls show all steps. thanks

7. You are given an unknown ML3X3 sample. To determine its structure, you measure an NMR spectrum of this sample and find that there are two sets of L signals in a 2:1 ratio and two sets of X signals in a 2:1 ratio. a. Propose a structure consistent with this NMR spectrum and assign its point group. Justify your structures in words. b. You are given a different sample, also with ML3X3 composition. This time, your NMR spectrum shows 1 set of L and I set of X signals. Propose a structure consistent with this NMR spectrum and assign its point group. Justify your structures in words
