Hydrazine-solvothermal methods to synthesize polymeric thioarsenates from one-dimensional chains to a three-dimensional framework

Abstract

Mn(ii)-thioarsenates [Mn(en)3]n[Mn6S(N2H4)4(AsS3)4]n (1), [N2H5]n[{Mn(N2H4)2(AsS4)}·0.5en]n (2), [Mn(trien){Mn(N2H4)(AsS3)}2]n (3), [Mn3(N2H4)6(AsS3)2]n (4), [Mn3(N2H4)6(AsS4)2]n (5), and [Mn(NH3)6]n[{Mn(NH3)(AsS4)}2]n (6) were prepared in N2H4 by solvothermal methods.

Structural Expansion of Chalcogenido Tetrelates in Ionic Liquids by Incorporation of Sulfido Antimonate Units

“…[42] The fact that the GeÀSb onds apparently are not influenced by neighboring [Ge 2 Sb 2 S 7 ] 2À cluster anions points at the absence of significant secondary interactions. The clustering of seven complex anions in 1 therefore seems to be driven by the nearly spherical shape of these assemblies, which are Scheme1.Overview of the synthesis of (Cat) 16 (2). The cations of compounds 1 and 2a are heavily disorderedi nthe crystal structures and could therefore not be determined by meanso fsingle-crystalX -ray diffraction, yet most probably,'Cat'r epresentst ris-alkylated imidazolium cations (C 4 C 1 C 1 Im) + ,a ccordingt os inglecrystal Raman spectroscopy(see below).…”

“…Approaches at moderate temperatures were particularly successful in the construction of a large diversity of architectures that would not be accessed with traditional solid state methods at high temperatures. Besides comparably established syntheses under solvothermal reaction conditions [16–20] or in alkali metal polychalcogenide flux, [21] reactions in ionic liquids have become a very popular method in more recent times for the transformation of chalcogenido (semi)metalates. The products are usually obtained as single‐crystalline material, which allows the subsequent investigation of their structural as well as concomitant physical properties [20, 22–29] …”
