The organic-inorganic hybrid [(C14H18N2)(Pb2I6)]n ([C14H18N2]2+ = N,N?-1,4-buthy- lenedipyridinium (BDP)) with one-dimensional structure was self-assembling synthesized by the organic quaternary ammonium template. It crystallizes in monoclinic, space group P21/n with a = 8.2596(9), b = 15.1363(19), c = 11.1603(13) , b = 97.915(5)o, C14H18N2Pb2I6, Mr = 1390.10, V = 1382.0(3) 3, Z = 2, Dc = 3.341 g/cm3, m(MoKa) = 18.870 mm-1, F(000) = 1196, the final R = 0.0420 and wR = 0.0921 for 2156 observed reflections with I > 2s(I). The title compound consists of cations ([C14H18N2]2+ ) and anion chain ([Pb2I62]n) which are combined by static attractive forces in the crystal. 展开更多

A novel coordinated polymer [(C22H50N2)(Ag2I4)]n([C22H50N2]2+ = N,N?-1,2- ethylence-bis(N,N?-dimethyl octane ammonium) (EDO)) was synthesized by the reaction of AgI and EDO at room temperature with pH = 6.8, and struc... A novel coordinated polymer [(C22H50N2)(Ag2I4)]n([C22H50N2]2+ = N,N?-1,2- ethylence-bis(N,N?-dimethyl octane ammonium) (EDO)) was synthesized by the reaction of AgI and EDO at room temperature with pH = 6.8, and structurally characterized by means of X-ray single- crystal diffraction. It crystallizes in triclinic, space group P1 with a = 9.6080(1), b = 12.7643(2), c = 7.2157(8) ? a = 100.835(8), ?= 91.030(3), ? = 91.297(9)o, (C21.50H48.50Ag2I4N2), Mr = 1058.46, V = 868.71(19) 3, Z = 1, Dc = 2.023g/cm3, F(000) = 497.5, ?MoKa) = 4.692 mm-1, the final R = 0.0623 and wR = 0.1949 for 2641 observed reflections with I > 2s(I). The title compound consists of cations ([C22H50N2]2+) and anion chain (Ag2I42-)∞ which are combined by static attracting forces in the crystal to form the so-called organic-inorganic hybrid material. 展开更多
