Perhaps you are asking about the Lewis Structure?

The molecular structure in the crystal form will be presented as the X-Ray crystal structure. The molecular structure for ionic compounds is fairly meaningless in solution. The ions dissociate and are usually surrounded by solvent molecules. That fraction that is present in solution in undissociated form is actually continuously forming ions; said ions are continuously reforming undissociated species.

Different solvents or ligands may have different crystal fields and solvent shells which result in different arrangements of ligands/solvent around ions. This phenomenon gives rise to ionic species that have different spectral properties in differing solvents or with different ligands. Search on Debye Huckel Theory, Crystal Field Theory and 10DQ.
