摘要：

Mn2SiSe4 has been synthesized at 800 degrees C. This compound cristallizes in the olivine-type structure with the cell parameters a = 13.3066(8) Angstrom, b = 7.7780(5) Angstrom and c = 6.2451(3) Angstrom in the Pnma space group. To date this structure type had been only reserved for oxides and sulfides. We report here the crystal structure determination of the first selenide with olivine structure. The magnetic measurements from 5 K to room temperature suggest the existence of preponderant antiferromagnetic interactions.
