摘要

通过原位单晶 X 射线衍射分析，研究了一种新化合物 Rb3SO4F 在宽温度范围内的晶体结构和热行为。该化合物在高达 377(10)℃ 的温度下保持稳定，并且在加热过程中不会发生相变。对热膨胀张量系数的计算表明，该结构具有强烈的各向异性膨胀：ab 平面上的热膨胀最大，而平行于 [001] 方向的热膨胀最小，这与以阴离子为中心的 FRb6 八面体中键长和角度的变化密切相关。

Rb3SO4F: Refinement of the Crystal Structure and Thermal Behavior

The crystal structure and thermal behavior of Rb₃SO₄F a new compound is studied by in situ single-crystal X-ray diffraction analysis in a wide temperature range. The compound is stable up to a temperature of 377(10)°C and does not undergo phase transitions during heating. Calculation of the coefficients of the thermal expansion tensor showed that the structure expands strongly anisotropically: the maximum thermal expansion is observed in the ab plane, while the minimum is parallel to the [001] direction, which is closely correlated to changes in bond lengths and angles in the anion-centered FRb₆ octahedron.
