  Gold at similar to 20 degrees C with F-2 in anhydrous hydrogen fluoride (aHF) acidified with SbF5 dissolves to a red solution from which orange Au-II(SbF6)(2) crystallizes on removal of volatiles. Au(SbF6)(2) is triclinic with a=5.300(1) Angstrom, b=5.438(1) Angstrom, c=8.768(2) Angstrom, alpha=76.872(3)degrees, beta=88.736(3)degrees, gamma=68.109(3)degrees, V=227.79(7) Angstrom(3), and Z=1, space group . Each Au(II) atom, at (1) over bar, is at the center of an elongated octahedron of F ligands; the four F's of the approximately square AuF4 unit are at 2.09(2) Angstrom x2 Angstrom and 2.15(2) Angstrom x2, each F provided by a different SbF6 species. The two long Au-F interatomic distances are at 2.64(2) Angstrom. The SbF6 are grossly distorted in their interactions with the Au. A cis pair of F ligands of each SbF6, make close approach to two different gold atoms, stretching Sb-F to 1.99(2) and 1.94(2) Angstrom. In each case the Sb-F distances trans to these stretched Sb-F bonds are short,being 1.85(2) and 1.84(2) Angstrom, respectively. Magnetic susceptibility measurements show antiferromagnetic coupling with a susceptibility decrease below 13 K. Solvolysis of Au-II(SbF6)(2) in aHF is accompanied by disproportionation: 4Au(SbF6)(2)-->Au+Au3F8+8SbF(5)(solv). Fluorination, at similar to 20 degrees C, of the solution of Au(SbF6)(2), in SbF5 acidified aHF, precipitates red crystals of triclinic Au-IISbF6}Au-2(II)(AuF4)-F-III}(2) with a(o)=5.2345(2) Angstrom, b(o)=8.1218(1) Angstrom, c(o)=10.5977(3) Angstrom, alpha=100.090(2)degrees, beta=100.327(2)degrees, gamma=104.877(2)degrees, V=416.63(2) Angstrom(3), space group , and Z=1. It is a simple paramagnet. The structure shows two different Au(II) environments, each approximately square-coordinated by F ligands, one being coordinated trans by an F ligand of each of two SbF6 and similarly by an F ligand from each of two (AuF4)-F-III species. The other Au(II) is approximately square-coordinated via bridging F ligands to four different (AuF4)-F-III species. Au-IISbF6}Au-2(II)(AuF4)-F-III}(2) with KAuF4 in aHF yields Au3F8 free of metallic gold,the simple paramagnetism of which indicates the formulation Au-II(AuF4)-F-III}(2).

  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).
