摘要：
Hydrothermal synthesis, thermal, spectroscopic and magnetic properties of Mn-5(HPO4)(2)(PO4)(2).4H(2)O. The Mn-5(HPO4)(2)(PO4)(2).4H(2)O compound has been synthesized by a hydrothermal technique under autogeneous pressure at 170degreesC. Its crystal structure consists of a three-dimensional network formed by MnO6 octahedra and HPO4 and PO4 tetrahedra. The thermal study indicated that the compound is stable up to 270degreesC. The magnetic measurements showed the presence of antiferromagnetic interactions with a T-N of approximately 12 K, and a spin-canting phenomenon at low temperature.
