摘要：

The low temperature structure of the T*-phase compound (La,Tb,Pb)2CuO4 was determined by single crystal x-ray diffraction at 50K. It is characterized by ordered canting of the CuO5 pyramids and corrugation of the CuO2 planes. The existence of two Cu sites with different valences in the CuO2 planes induces charge ordering which is detrimental for superconductivity.
