The ternary oxide MnReO4, manganese rhenium oxide, has been synthesized under a high pressure of 5.5 GPa at 1473 K and its crystal structure has been determined by single-crystal X-ray diffraction. MnReO4 crystallizes in a wolframite-type structure with average bond lengths of 〈Re—O〉 = 1.935 and 〈Mn—O〉 = 2.160 Å that are in good agreement with the ionic radii of Re6+ and Mn2+. The magnetic properties of MnReO4 have been studied by SQUID measurements, revealing magnetic ordering below 275 (10) K and a weak ferromagnetic component of the ordered magnetic structure.
