title: Preparation, crystal structure and magnetic properties of the high-pressure phase MnReO4 with a wolframite-type structure.
abstract: The ternary oxide MnReO(4), 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. MnReO(4) crystallizes in a wolframite-type structure with average bond lengths of Re-O = 1.935 and Mn-O = 2.160 A that are in good agreement with the ionic radii of Re(6+) and Mn(2+). The magnetic properties of MnReO(4) have been studied by SQUID measurements, revealing magnetic ordering below 275 (10) K and a weak ferromagnetic component of the ordered magnetic structure.
