Synthesis,crystal structures,and electronic properties of one dimensional Ba_(9)Sn_(3)(Te_(1-x)Se_(x))_(15)(x=0-1)
摘要
In this work,the Ba_(9)Sn_(3)Te_(15)compound has been synthesized for the first time under high pressure and high temperature conditions.Single-crystal X-ray diffraction analysis shows that Ba_(9)Sn_(3)Te_(15)crystallizes into a hexagonal structure with a space group of P6c2(188)and lattice parameters of a=b=10.2403(1)A,and c=20.7720(2)A.The crystal structure contains trimeric one-dimensional chains with face-sharing SnTe6 octahedrons stacked along the c-axis.These chains are arranged in a triangular lattice in the ab plane.
