Abstract

A review of structural studies of silver borates with a salt inclusion structure is presented. Besides the presentation of the first halogen-containing silver borates, we discuss the structural and physicochemical characterization of the Ag₄B₄O₇X₂ (X = Br, I), Ag₃B₆O₁₀X (X = Br, I, NO₃), and Ag₄B₇O₁₂X (X = Cl, Br, I) families, as well as the Ag₄(B₃O₆)(NO₃) and Ag₃B₄O₆(OH)₂(NO₃). The dimensionality of their crystal structures varies from three to two or zero. In the majority of cases, the silver atoms exhibit strong anharmonicity of thermal displacements, which was studied by X-ray structural analysis, including polythermic. We discuss the reasons for the low stability of chlorine-containing silver borates, as well as the relationships between the anharmonicity of thermal displacements and other properties, including the high ionic conductivity of Ag₃B₆O₁₀I.

具有盐包体结构的硼酸银的晶体化学

综述了具有盐包体结构的硼酸银的结构研究进展。除了首次提出含卤素硼酸银外，我们还讨论了Ag4B4O7X2 (X = Br， I), Ag3B6O10X （X = Br， I, NO3）和Ag4B7O12X （X = Cl, Br， I）家族以及Ag4(B3O6)（NO3）和Ag3B4O6(OH)2（NO3）的结构和物理化学性质。它们的晶体结构的维数从三到二或零不等。在大多数情况下，银原子表现出强烈的热位移非调和性，这是通过x射线结构分析研究的，包括多热。我们讨论了含氯硼酸银稳定性低的原因，以及热位移的非调和性与Ag3B6O10I的高离子电导率等其他性能之间的关系。
