Hypothesis
The study aims to redetermine the crystal structure of 6,6′-dimethoxy-2,2′-[hexane-1,6-diylbis(nitrilodimethylidyne)]diphenol.
Conclusion
The study found that one molecule crystallizes in a neutral form while the other crystallizes in a zwitterionic form.
Supporting Evidence
- The study identified two independent centrosymmetric molecules in the compound.
- Significant differences in bond lengths supported the existence of zwitterionic and neutral forms.
- Intermolecular hydrogen bonds were observed forming one-dimensional chains in the crystal.
Takeaway
The researchers looked at a chemical compound and found that it can exist in two different forms, one neutral and one charged.
Methodology
The crystal structure was determined using X-ray diffraction techniques.
