CH3NH3PbX3, ein Pb(II)-System mit kubischer Perowskitstruktur / CH3NH3PbX3, a Pb(II)-System with Cubic Perovskite Structure

  • Dieter Weber

Abstract

CH3NH3PbX3 (X = Cl, Br, I) has the cubic perovskite structure with the unit cell parameters a = 5,68 Å (X = Cl), a = 5,92 A (X = Br) and a = 6,27 A (X = I). With exception of CH3NH3PbCl3 the compounds show intense colour, but there is no significant conductivity under normal conditions. The properties of the system are explained by a "p-resonance-bonding". The synthesis is described.
