摘要

通过一锅法合成了透明的白色结晶产物K[（C2F5）3PF3]（KFAP）。二氟三（五氟乙基）磷烷首先与HF水溶液反应，然后在溶液中与K2CO3或KHCO3反应。未进行中间体三（五氟乙基）三氟磷酸H[（C2F5）3PF3]（HFAP）的分离。通过粉末和单晶X射线衍射对盐进行了表征。单晶结构显示出一种单周期配位聚合物，其中存在K∙∙F桥接相互作用。通过TGA-DSC同时测量，确定了KFAP的热特性和行为。

Potassium Trifluorotris(pentafluoroethyl)phosphate

A transparent white crystalline product, K[(C2F5)3PF3] (KFAP), has been synthesized via a one-pot route. Difluorotris(pentafluoroethyl)phosphorane was reacted first with aqueous HF then with K2CO3 or KHCO3 in a solution. Isolation of the intermediate, tris(pentafluoroethyl)trifluorophosphoric acid H[(C2F5)3PF3] (HFAP), was not carried out. The salt has been characterised by powder and single crystal X-ray diffraction. The single-crystal structure shows a monoperiodic coordination polymer involving K∙∙∙F bridging interactions to be present. The thermal characteristics and behaviour of KFAP have been established by simultaneous TGA-DSC measurements.
