摘要
Abstract The crystal structure of the 3R polytype with the lattice parameters а = 3.82 Å, с = 63.41 Å, sp. gr.R3m，并建立了 TO\({{\bar {text\{T}}}}\)POOP 结构类型（T 和 \({\bar {text\{T}}}}\) 是相对定向的四面体层，O 是八面体层，P 是部分填充的包间层）。此外，还建立了超晶格周期为А1,2 = \(\sqrt 7 \)а的超结构，这种超结构是由于 OOP 包中的铟占据了每个八面体的 6/7 而形成的；还建立了超晶格周期为А3 = 2а的超结构，这种超结构是由于在 TO（{{\bar {\\{T}}}}\ ）P 包所包含的八面体上分布了 3/4 的铟原子和 1/4 的空位而形成的。研究表明，样品中不同的硫含量会导致TO（{\bar {text\{T}}}}）P包八面体层中阳离子的过量和上层结构的破坏。
Effect of Sulfur Deficiency on the Structural and Superstructural Features of Ga1.29In3.38S7
The crystal structure of the 3R polytype with the lattice parameters а = 3.82 Å, с = 63.41 Å, sp. gr. R3m, and the TO\({{\bar {\text{T}}}}\)POOP structural type (T and \({{\bar {\text{T}}}}\) are oppositely oriented tetrahedral layers, O are octahedral layers, P are partially filled interpacket layers) has been established. Superstructures with superlattice period А1,2 = \(\sqrt 7 \)а, formed as a result of occupation of 6/7 of each octahedron with indium in the OOP packet, and a superstructure with the superlattice period А3 = 2а, formed by the distribution of 3/4 of In atoms and 1/4 vacancies over the octahedra included in the TO\({{\bar {\text{T}}}}\)P packet, are also established. It is shown that the different sulfur content in the samples leads to a different excess of cations in the octahedral layers of the TO\({{\bar {\text{T}}}}\)P packets and destruction of the superstructure.
