摘要：
A new quinternary oxide, NaTl3Cu4Te2O12, has been synthesized and characterized by single crystal X-ray diffraction. The reported material was synthesized by hydrothermal techniques using TlNO3, CuO, TeO2, and NaOH as reagents. The material exhibits a two-dimensional layered structure consisting of edge-shared CuO6 and TeO6 polyhedra separated by Na+ and Tl+ cations. NaTl3Cu4Te2O12 crystallizes in space group C2/m with a = 12.9800(17) angstrom, b = 9.3455(12) angstrom, c = 5.2335(7) angstrom, beta = 104.276(2)degrees, V = 615.24(14) angstrom(3), and Z = 2.
