  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).

  Synchrotron radiation X-ray powder diffraction data (SPDD) have been obtained for Ag[AgF4](2), Au[AuF4](2), Ag[AuF4], and Ag[AuF4](2). Ag[AgF4](2) and Au[AuF4](2) are isostructural with Ag[AuF4](2), space group (SG) P2(l)/n, Z = 2, with the following: for Ag[AgF4](2) a = 5.04664(8), b = 11.0542(2), c = 5.44914(9) Angstrom, beta 97.170(2)degrees; for Au[AuF4](2) a = 5.203(2), b = 11.186(3), c = 5.531(2) Angstrom, beta 90.55(2)degrees. The structure of Ag[AgF4](2) was refined successfully (SPDD) applying the Rietveld method, yielding the following interatomic distances (Angstrom): Ag-II-F = 2.056(12), 2.200(13), 2.558(13); Ag-III-F = two at 1.846(12), others = 1.887(12), 1.909(13), 2.786(12), 2.796(12), 2.855(12). AgAuF4, like other AA'F-4 salts (A = Na-Rb; A' = Ag, Au), crystallizes in the KBrF4 structure type, SG I4/mcnn (140), Z = 4 with a = 5.79109(6), c 10.81676(7) Angstrom. SPDD gave (in Angstrom) four Au-III-F = 1.89(1) and eight Ag-I-F = 2.577(7). SPDD for AgAuF6 confirmed that it has the LiSbF6 structure, 15.0451(6) Angstrom. SG R (3) over bar, Z = 3, with a = 5.2840(2), c = 15.0451(6) Angstrom.
