摘要

Single crystal of KPb_2Br_5 has been grown using the Bridgman technique. Initially the synthesis of stoichiometric KPb_2Br_5 compound was performed from high purity bromide salts. Electronic structure of KPb_2Br_5 has been determined with X-ray photoelectron spectroscopy for powdered sample fabricated by grinding in air. Drastic chemical interaction of KPb_2Br_5 with atmosphere has not been detected. Chemical bonding in potassium- and lead-containing bromides is considered using binding energy differences ⊿K=(BE K2p_(3/2)-BE Br 3d) and ⊿_(ph)=(BE Pb 4f_(7/2)-BE Br 3d), respectively, as representative parameters.
