First-principles band-structure calculations and X-ray photoelectron spectroscopy studies of the electronic structure of TlPb2Cl5

[Display omitted] •Electronic structure of TlPb2Cl5 is calculated by the FP-LAPW method.•The valence band is dominated by contributions of Cl 3p states.•Contributions of Pb 6p* states dominate at the bottom of the conduction band.•The FP-LAPW data allow concluding that TlPb2Cl5 is an indirect-gap ma...
