摘要：

The crystal structure of TlCu3Se2 has been refined (RF = 0.050, RwF = 0.045; 349 reflections, 37 parameters) from X-ray single-crystal diffraction data. The compound is of the CsAg3S2 type, space group C2/m, with the cell parameters a = 15.2128(7) A ̊, b = 4.0115(2) A ̊, c = 8.3944(4) A ̊ and β = 111.700(4)°. Comparison is made with the Tl5Cu14Se10 structure that can be derived from a TlCu3Se2 arrangement by a modified stacking sequence of common slabs, accommodating the slight copper deficiency. © 1990.
