Sumario:A mixed-valence manganese selenite, Mn(3)O(SeO(3))(3), was successfully synthesized using a conventional hydrothermal method. The three-dimensional framework of this compound is composed of an MnO(6) octahedra and an SeO(3) trigonal pyramid. The magnetic topological arrangement of manganese ions shows a three-dimensional framework formed by the intersection of octa-kagomé spin sublattices and staircase-kagomé spin sublattices. Susceptibility, magnetization and heat capacity measurements confirm that Mn(3)O(SeO(3))(3) exhibits two successive long-range antiferromagnetic orderings with T(N1)~4.5 K and T(N2)~45 K and a field-induced spin–flop transition at a critical field of 4.5 T at low temperature.
