A one dimensional coordination polymer, [(C7H18N)(Ag2l3)]n((C7H18N)^ =Methyltriethylammonium) has been successfully synthesized and characterized by X-ray single-crystal diffraction method. Structure analysis shows that the compound consists of organic cations(Methyltriethylammonium) and inorganic anion chains (Ag2l3)s^-.The inorganic moiety consists of AgI4 tetrahedron, which shares the same edges with adjacent AgI4 tetrahedrons to form one-dimensional infinite double chains along a-axis. There exists weak interaction among Ag…Ag atoms in the crystal. Anion chains are surrounded by Methyhriethylammonium cations. Anion chains and cations are in combination with each other by static attracting forces in the crystal to form so-called organic-inorganic hybrid structure. According to the crystal structure data, quantum chemistry calculation with DFT on B3LYP level was used to reveal the electronic structure of title compound. CCDC: 254288. 相似文献

A novel coordination polymer [(C10H16N)2(Pb2I6)·2DMF·H2O]n (C10H16N=N-butyl-2-Methy-Pyridinium) was synthesized by the reaction of Pb(NO3)2 with C6H10NI at room temperature in DMF solvent and structurally characterized by means of X-ray single diffraction. The title compound crystallizes in triclinic system, space group P1 with a=1.1237(2) nm, b=1.25330(16) nm, c=0.808 00(12) nm, α=102.523(4)°, β=92.475(5)°, γ=95.712(10)°, V=1.102 9(3) nm3, Z=1, Dc=2.470 Mg·m-3, F(000)=738, chemical formula C26H48N4O3Pb2I6 and Mr=1 640.46, μ(MoKα)=11.849 mm-1, the final R=0.057 8 and wR=0.166 5 for 3716 observed reflections with I > 2σ(I). The title compound consists of cations ([(C10H16N)+] and anion chain(PbI3-),they are combined by static attracting forces in the crystal. DMF and H2O locate between the organic and inorganic moiety.

1 INTRODUCTION The influence of organic components on the mi- crostructures of inorganic solids has been extensively reported in recent years and shown to provide an efficacious method for the design of new materials[1~3]. Owing to their potential applications as new func- tional solid materials, interest in self-assembled co- ordination polymers with novel physical properties has grown rapidly[4~7], and many complexes like Bu4N[Ag3I4][8], {[(n-C4H9)4N]2Ag4.95Cu(I)1.05I8}n[9], [C6H… 相似文献

Using 1,1?-bis(isoquinoline)-1,4-phenyldimethylenyl(BIQPM2+) cation as template, a new tetrameric(Bi4 I16)4-iodobismuthate-containing hybrid with formula of(BIQPM)2(Bi4 I16)·H2 O(1), has been prepared under solvothermal conditions. The centrosymmetric Bi4-4 I16 tetraanion is constructed from four edge-shared slightly distorted BiI6 octahedrons. Due to the presence of larger conjugated system(isoquinoline ring), strong π···π stacking interactions can be observed. Besides, strong I···I interactions can be monitored and extends the 0-D Bi4 I4-16 cluster to a quasi-1-D chain. The smaller energy gap of 2.13 eV is led by these non-covalent interactions. Its infrared emission might be caused by strong charge transfer between anions and cations. Furthermore, the reversible thermochromic behavior with low chromotropic temperature of 80 ℃ can be observed, whose mechanism was discussed. 相似文献
