  • In this work we describe the synthesis and characterization of the Co2Cu4Te4O11Cl4 phase prepared by the hydrothermal technique. From the polycrystalline X-ray diffraction pattern the obtained new phase was indexed in the P-l space group with cell parameters a= 9.274(7), b= 12.132(2), c= 9.252(2) Å, á = 98.18(14), ß = 108.22(13) and γ = 111.07(8) °. The nominal composition and morphology were obtained using SEM-EDX measurements. The optical band gap of the material corresponds to an insulating system with 2.7 eV, and the thermogravimetric data shows that the phase is stable up to 700 °C.
