摘要

The compounds Rb2Mn3Se4, Cs2Mn3Se4, Rb2Mn3Te4 and Cs2Mn3Te4 were synthesized by the reaction of alkali metal carbonates with chalcogen and Mn or MnCO3 in a stream of hydrogen charged with chalcogen. Structural investigations show that all compounds crystallize in isotypic atomic arrangements (Cs2Mn3S4-type, space group Ibam, Z = 4). Additionally neutron diffraction experiments were carried out and yielded the spin structures of Rb2Mn3Se4 and Cs2Mn3Se4 (Shubnikov space group Ibam'). The structural related selenides ALiMnSe(2) and ALiZnSe(2) (A = K, Rb or Cs) were synthesized by analogous reactions. All these compounds are isotypic and crystallize in the BaZn2P2-structure type.
