摘要：

Single crystals of Y2Cu2O5 were obtained in the flux growth process by controlled heating of a mixture of Y2O3, BaO, and CuO in a molar ratio of 1:8:20. These crystals were analyzed by a single-crystal X-ray diffraction analysis. The crystal contains polymeric chains of Cu2O5 interspersed by yttrium ions surrounded by octahedral arrangements of oxygen atoms. Crystal data: space group = Pna2(1), a = 10.799(2) angstrom, b = 3.4990(5) angstrom, c = 12.459(2) angstrom, Z = 4, 380 reflections, R = 0.026, R(w) = 0.030.
