Description
Summary:A transparent white crystalline product, K[(C[sub.2] F[sub.5] )[sub.3] PF[sub.3] ] (KFAP), has been synthesized via a one-pot route. Difluorotris(pentafluoroethyl)phosphorane was reacted first with aqueous HF then with K[sub.2] CO[sub.3] or KHCO[sub.3] in a solution. Isolation of the intermediate, tris(pentafluoroethyl)trifluorophosphoric acid H[(C[sub.2] F[sub.5] )[sub.3] PF[sub.3] ] (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.
