用肼-水热法成功地合成了两种同结构的四元硫属锑酸盐BaCuSbQ_3（Q = S，Se）：BaCuSbS_3（1）和BaCuSbSe_3（2）。这两种化合物均属于正交晶系，具有三维孔道结构，由CuQ 4和SbQ 3畸变四面体单元通过顶点共享构成[Cu 2Sb 2 Q6]4-骨架。光学性质和理论研究表明，1和2是具有窄带隙的半导体。此外，还研究了它们的光电化学性质。
Two isostructural quaternary chalcogenidoantimonates(III) BaCuSbQ3(Q = S, Se): BaCuSbS3(1) and BaCuSbSe3(2) have been successfully synthesized through a facile hydrazine-hydrothermal method. Both two compounds crystallize in the orthorhombic space group and feature a three-dimensional (3D) channeled [Cu2Sb2Q6]4-framework, which is constructed by the distorted tetrahedral CuQ4and pyramid SbQ3units via vertex sharing. Both optical properties and theoretical studies show1and2are semiconductors with narrow band gaps. In addition, their photoelectrochemical properties have been investigated.
