  Room Temperature Syntheses of AuF₆^- and PtF₆^- Salts, Ag⁺AuF₆^-, Ag²⁺PtF₆^2-, and Ag²⁺PdF₆^2-, and an Estimate for E(MF₆^-) [M = Pt, Pd]

  摘要：

  Solutions of AuF4- or PtF62- salts, prepared from the metals at similar to 20 degrees C, in liquid anhydrous hydrogen fluoride (aHF), made basic with alkali fluorides, are further oxidized by photodissociated F-2 (visible or near-UV Light) to give AuF6- or PtF6- salts, including O2+AuF6- (with O-2 in the F-2). Similar photochemical oxidation of PdF62- salts does not occur. This new synthetic approach has provided LiAuF6 and LiPtF6 for the first time, each of which has the LiSbF6 type () structure with (hexagonal cell): LiAuF6, a = 4.9953(9) Angstrom, c = 13.704(3) Angstrom, V/Z = 98.71(6) Angstrom(3); LiPtF6, a = 5.0236(7) Angstrom, c = 13.623(2) Angstrom, V/Z = 99.25(5) Angstrom(3). Interaction of AuF6- with Ag+ gives Ag+AuF6- (, a = 5.283(3) Angstrom, c = 15.053 Angstrom, V/Z = 121.3(2) Angstrom(3)), whereas PtF62- or PdF62- stabilize Ag2+ as Ag2+Pt(Pd)F-6(2-) (; AgPtF6: a = 5.049(8) Angstrom, c = 14.46(2) Angstrom, V/Z = 106.4(5) Angstrom(3); and AgPdF6, a = 5.00(4) Angstrom, c = 14.6(2) Angstrom, V/Z = 105(3) Angstrom(3)). New cubic modifications (probable space group Ia3) have been found for AgMF6 (M, a value, Angstrom): Ru, 9.653(10); Os, 9.7318(9); Ir, 9.704(2). The preference for Ag2+Pt(Pd)F-6(2-) over Ag+Pt(Pd)F-6(-) is attributed to a second electron affinity of Pt(Pd)F-6, E(Pt(Pd)F-6(-)) > 60 kcal mol(-1).

  It is established that krypton difluoride (KrF2) interacts with metallic gold in anhydrous hydrogen fluoride (HF) in the presence of alkaline and alkaline-earth metal fluorides with the formation of complex hexafluoroaurates with the general formula (MAuF6)-Au-I-F-V (M-I = Li, Na, K, Rb, Cs) and bis-hexafluoroaurates M-II((AuF6)-F-V)(2) (M-II = Mg, Ca, Sr, Ba). As a result of the subsequent interaction of bis-hexafluoroaurates with krypton difluoride, new coordination compounds with the composition M-II((AuF6)-F-V)(2) center dot nKrF(2) (M-II = Ca, Sr, Ba; n = 0-4) were synthesized. The Raman spectra were studied and a comparative analysis of the Raman spectra of the obtained compounds was performed. The possible variants of the structural transformation of the AuF (6) (-) anions in compounds and the position and character of the chemical bond of the "guest" (KrF2) in these compounds are discussed.
