摘要：

The thermal behaviour of two coordination compounds [MnDy(malic)(3)].5H(2)O and [MnDy(gluconic)(3)].12H(2)O has been studied to evaluate their suitability for dysprosium manganese perovskite synthesis. A decomposition scheme is proposed leading to perovskites with orthorhombic (malic precursor) and hexagonal (gluconic precursor) structures which were obtained after a heating treatment of 4 h at 1000degreesC with one-hour plateau at 500degreesC.
