Materials Data on SF4 by Materials Project

SF4 is beta-like structured and crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of eight sulfur tetrafluoride molecules. S4+ is bonded in a rectangular see-saw-like geometry to four F1- atoms. There are a spread of S–F bond distances ranging from 1.58–1.72 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one S4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one S4+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one S4+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one S4+ atom.四氟化硫（SF4）具有类β结构，结晶于正交晶系P2₁2₁2₁空间群。该结构为零维结构，包含8个四氟化硫分子。S⁴+以类矩形跷跷板的几何构型与4个F1-原子成键，S–F键的键长分布范围为1.58–1.72 Å。体系中存在4个不等价的F1-位点：在第一个F1-位点中，F1-以单键几何构型与1个S⁴+原子成键；在第二个F1-位点中，F1-以单键几何构型与1个S⁴+原子成键；在第三个F1-位点中，F1-以单键几何构型与1个S⁴+原子成键；在第四个F1-位点中，F1-以单键几何构型与1个S⁴+原子成键。
