Das System TlClPbCl2

A reinvestigation of the x-T diagram was performed using DTA and X-ray techniques. Four compounds exist in the sytem of $\text{TlCl}\text{PbCl}{}_2$. The transformations of Tl₃PbCl₅ and TlPb₂Cl₅ are discussed. The compound Tl₂PbCl₄ exists only within a temperature interval of about 20°C. A compound of the formula Tl₇Pb₃Cl₁₃ is reported for the first time. Crystallographic data of TlPb₂Cl₅, high and low Tl₃PbCl₅, and Tl₇Pb₃Cl₁₃ are presented.
