摘要：

The rich materials class of iron-based superconductors turned out to exhibit a very complex electronic structure despite the simplicity of their crystal structures. For various approaches to study the instability against magnetic order or superconductivity, a real-space description of the electronic structure is required. Here, the bonding situation and the orbital structure of the electronic state are analyzed and minimum tight-binding models quantitatively correctly describing the low-energy electronic structure are provided.
