中文摘要	Fifteen new rare-earth transition-metal chalcogenides, Ln(3)MGaS(7) (Ln=Nd, Sm, Dy, Er; M=Co, Ni) and Ln(3)MGaSe(7) (Ln=Nd, Sm, Gd, Dy, M=Co; Ln=Nd, Gd, Dy, M=Ni), have been synthesized by solid state reactions. They are isostructural, adopt Ce3Al1.67S7-related structure type, and crystallize in the non-centrosymmetric hexagonal space group P6(3). They adopt a three-dimensional framework composed of LnQ(7) monocapped trigonal prisms with the interesting [MQ(3)](4-) chains and isolated GaQ(4) tetrahedra lying in two sets of channels in the framework. The magnetic susceptibility measurements on Ln(3)CoGaQ(7) (Ln =Dy, Er, Q=S; Ln =Dy, Q=Se) indicate that they are paramagnetic and obey the Curie-Weiss law over the entire experimental temperature, while the magnetic susceptibility of Sm3CoGaSe7 deviates from the Curie-Weiss law as a result of the crystal field splitting.
