Discussion Overview

The discussion revolves around the search for the molecular structure of CuSO4·5H2O, ZnSO4·7H2O, and FeSO4·7H2O, with participants exploring different interpretations of "structure" including crystal and molecular forms.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses difficulty in finding the structures in literature and online, specifically mentioning J.D. Lee.
  • Another participant suggests that the inquiry might pertain to crystal structure, hinting at X-ray crystallography.
  • A different participant clarifies that they are looking for molecular structure rather than crystal structure.
  • There is a suggestion that the Lewis structure might be relevant, with a note that the molecular structure of ionic compounds is less meaningful in solution due to dissociation.
  • One participant mentions the influence of different solvents or ligands on the arrangement of ions and their spectral properties.
  • A participant references diborane as an example of a molecular structure with unique bonding characteristics.
  • Another participant emphasizes the need for clarity on Lewis structures and suggests looking up resources for assistance.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the specific type of structure being sought, with some focusing on molecular structures and others on crystal structures. The discussion remains unresolved regarding the exact nature of the structures in question.

Contextual Notes

There are limitations in the discussion regarding the definitions of "structure" and the context in which the structures are being considered, particularly the distinction between solid and solution states.

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.
