SUMMARY
The forum discussion centers on doping rutile TiO2 using Quantum ESPRESSO v5.0.1, specifically by substituting a nitrogen atom for a titanium atom. Users reported that the nitrogen atom did not form bonds with nearby atoms when visualized in XCRYSDEN. The issue arises from XCRYSDEN's bond visualization, which relies on predefined atomic types and distances rather than the actual physical interactions in the system. Adjusting the bond parameters in XCRYSDEN can resolve the visualization issue without affecting the underlying physics.
