The metal-insulator transition (MIT) of $\chem{V_6O_{11}}$ is studied by means of electronic structure calculations using the augmented spherical wave method. The calculations are based on density functional theory and the local density approximation. Changes of the electronic structure at the MIT are discussed in relation to the structural transformations occurring simultaneously. The analysis is based on a unified point of view of the crystal structures of $\chem{V_6O_{11}}$, $\chem{VO_2}$, and $\chem{V_2O_3}$. This allows to group the electronic bands into states behaving similarly to the dioxide or the sesquioxide. While the sesquioxide-like $\chem{V}$ $3d_{yz}$ states show rather weak changes on entering the low-temperature stru...
