摘要：

The chain Mn(III) fluoride Na2MnF5 has been studied by means of neutron powder diffraction. Below T(N) = 11.1(5) K, a 3D intrachain antiferromagnetic coupling is observed: this is the first time that a 3D ordering is unambiguously found in anhydrous A2MnF5 series. Additionally a magnetic frustration phenomenon is found for the interchain ordering. At 1.5 K the magnetic structure is colinear, with the manganese magnetic moments (3.3(1) mu(B)) parallel to the a axis. Structural and magnetic data of Na2MnF5 are compared with those of other related compounds.
