SUMMARY

The discussion focuses on the molecular structures of CuSO4·5H2O, ZnSO4·7H2O, and FeSO4·7H2O. Participants clarify that the molecular structure in solution is less meaningful due to ion dissociation, and suggest searching for X-ray crystal structures for solid forms. Key theories mentioned include Debye-Hückel Theory and Crystal Field Theory, which explain the behavior of ions in different solvents. The conversation emphasizes the importance of understanding Lewis structures for these compounds.

PREREQUISITES
  • Understanding of X-ray crystallography
  • Familiarity with Lewis structures
  • Knowledge of Debye-Hückel Theory
  • Basic concepts of Crystal Field Theory
NEXT STEPS
  • Research X-ray crystal structures of CuSO4, ZnSO4, and FeSO4
  • Study Lewis structures and their applications in ionic compounds
  • Explore Debye-Hückel Theory for understanding ionic behavior in solutions
  • Investigate Crystal Field Theory and its implications for ligand arrangements
USEFUL FOR

Chemistry students, researchers in inorganic chemistry, and professionals studying ionic compounds and their structures will benefit from this discussion.

I need to find the structure ofCuSO_4.5H_2O, ZnSO_4.7H_2O and FeSO_4.7H_2O.

Ive looked at J.D. Lee for them but can't seem to find them, maybe I am looking in the wrong place. I can't find something worthwhile on the net either. All I seem to hit are actual pictures of the salts/solutions but not the actual structure. Please help. If you can point out a link or something, Id be really greatful.
 
Physics news on Phys.org
Someone...? Anyone...? Please...?
 
Are you asking about crystal structure (face centered cubic)?

If so, try searching for X-ray crystal structure of...
 
no... that not what I am looking for... I am looking for the molecular structure...
 
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.
 
Yeah, I think its the Lewis structure I am looking for. Like diborane has the sturcture with the banana bonds (3c-2e bonds).
 
Nobody knows the molecular structure? I am not talking about the structure in solution... the anhydrous form...
 
Review the rules for determining Lewis structures.

If you are having difficulty, google "lewis dot structures". There are useful resources that will assist you.
