  Structures and Related Properties of AgX Bearing 3,3‘-Thiobispyridine (X^- = NO₃^-, BF₄^-, ClO₄^-, and PF₆^-)

  摘要：

  Infinite molecular helices [Ag(3,3 ' -Py2S)]X (3,3 ' -Py2S = 3,3 ' -thiobispyridine; X- = BF4-, ClO4-, and PF6-) have been rationally constructed or induced. Crystallographic characterization (X- = BF4-, monoclinic P2(1)/n, a = 8.946(3) Angstrom, b = 14.130(2) Angstrom, c 10.124(2) Angstrom, beta = 107.83(2)degrees, V = 1218.3(5) Angstrom (3), Z = 4, R = 0.0351; X- = ClO4-, monoclinic P2(1)/n, a = S.884(1) Angstrom, b = 14.305(3) Angstrom, c = 10.110(1) Angstrom, beta = 106.78(1)degrees, V= 1230.1(3) Angstrom (3), Z = 4, R = 0.0417; X- = PF6-, monoclinic P2(1)/c, a = 10.959(2) Angstrom, b = 9.808(2) Angstrom, c = 14.065(3) Angstrom, beta = 112.03(2)degrees, V = 1401.4(5) Angstrom (3), Z = 4, R = 0.0442) reveals that the skeletal structure is an oblong cylindrical cationic helix consisting of alternating Ag(I) and 3,3 ' -Py2S species and that its counteranions are pinched in two columns inside each helix. The formation of the helical coordination polymer appears to be primarily associated with a suitable combination of the skewed conformer of 3,3 ' -Py2S and the potential linear geometry of the N-Ag(I)-N bond. However, the framework of the nitrate analogue [Ag(3,3 ' -Py2S)NO3] (monoclinic P2(1)/c, a = 8.177(2) Angstrom, b = 10.291(1) Angstrom, c 14.771(2) Angstrom, beta = 102.19(1)degrees V = 1214.9(4) Angstrom (3), Z = 4, R = 0.0300) is a two-dimensional network consisting of an 18-membered ring unit, where each 3,3 ' -Py2S acts as a N,N ' ,S- tridentate ligand connecting three tetrahedral silver(Ij ions with the monodentate nitrate weakly bonded to the silver (Ag . . .O = 2.65(1) Angstrom) rather than acting as a counteranion. The anion exchange of [Ag(3,3 ' -Py2S)-NO3] with BF4-, ClO4-, or PF6- has been accomplished in aqueous media. The two-dimensional networks are easily converted into the helices via the anion exchange, but the reverse anion exchange proceeds slightly. Thermal analyses indicate a relationship between the thermal stabilities and the structural properties.
