Abstract
Mn2SiSe4 has been synthesized at 800 degrees C. This compound cristall izes in the olivine-type structure with the cell parameters a = 13.306 6(8) Angstrom, b = 7.7780(5) Angstrom and c = 6.2451(3) Angstrom in th e Pnma space group. To date this structure type had been only reserved for oxides and sulfides. We report here the crystal structure determi nation of the first selenide with olivine structure. The magnetic meas urements from 5 K to room temperature suggest the existence of prepond erant antiferromagnetic interactions.
