| Abstract: | A novel coordination polymer (C8H20N)(Ag2I3)]n (C8H20N]+ = tetraethyl ammo- nium (TEA)) was synthesized by the reaction of AgI and C8H20NI at room temperature with pH = 6.5, and structurally characterized by means of X-ray single-crystal diffraction.It crystallizes in orthorhombic, space group Pna21 with a = 7.3323(9), b = 18.250(2), c =12.5294(15) (A), C6.33H16.16NAg2I3, Mr = 702.76, V = 1676.6(4) (A)3, Z = 4, Dc = 2.784 g/cm3, F(000) = 1256.6, μ(MoKα) = 7.828 mm-1, the final R = 0.0529 and wR = 0.1586 for 1189 observed reflections with I > 2σ(I).X-ray analysis shows that the Ag2I3]n- chain is built up by AgI4 tetrahedron and in combination with quaternary ammonium cations (C8H20N]+) by static attractive forces to form the so-called organic-inorganic hybrid material. |
