中文摘要	The first series of rare-earth chalcogenides with mixed-valence Sn atoms, namely the BaLnSn(2)Q(6) (Ln = Ce, Pr, Nd, Q = S; Ln = Ce, Q = Se) compounds, were synthesized via stoichiometric solid-state reactions at 1100 degrees C. BaLnSn(2)Q(6) belong to the polar space group Pmc2(1) of the orthorhombic system and contain mixed valent Sn atom in the ratio of Sn2+/Sn4+ = 1:3. In the structure, the Sn(2+)Q(5) rectangular pyramids, Sn(4+)Q(5) trigonal bipyramids, Sn(4+)Q(6) octahedra, and LnQ(8) bicapped trigonal prisms are connected with each other to form a three-dimensional framework with interspaces occupied by Ba2+ cations. As deduced from magnetic susceptibility measurements, BaPrSn2S6 and BaNdSn2S6 are paramagnetic and obey the Curie-Weiss law.
