Crystallographic data for 1： C10H8N2CdI2, monoclinic system, space group C2/c, a = 16.927（1）, b = 10.0925（7）, c = 7.7422（3） A, β = 106.0629（4）°, V = 1271.00（14） A^3, Z = 4, F（000） = 944,/a = 6.546 mm^-1, Dc= 2.730 g/cm^3, Mr = 522.38, the final R = 0.0309 and wR = 0.0805 for 1310 observed reflections （I 〉 20（I））. X-ray crystal structure analysis shows that the Cd atom is coordinated by four iodines and two N atoms from one 2,2＇-bipy to form an 1-D chain-like structure through bridging iodines. The fluorescene of the title compound was also discussed.展开更多
Two bifunctional amines, 4-(2-aminoethyl)morpholine and histamine, were heated with PbI_2 and BiI_3 in concentrated HI aqueous solution to give one-dimensional(1D) organicinorganic hybrid compounds [(C_6H_(16)N_2O)PbI...Two bifunctional amines, 4-(2-aminoethyl)morpholine and histamine, were heated with PbI_2 and BiI_3 in concentrated HI aqueous solution to give one-dimensional(1D) organicinorganic hybrid compounds [(C_6H_(16)N_2O)PbI4]n(1) and [(C_(16)H_(20)N_(20))Bi_2I_(10)](2), respectively. In 1, the [PbI6] octahedra formed double chain anions through sharing-corner and-edge, and the protonated(C_6H_(16)N_2O)^(2+) cations were located at the vicinity of the double chains by hydrogen bonds. In 2, the [BiI_6] octahedra firstly formed dimeric [Bi_2I_(10)]^(4-) anion through sharing edge, and subsequently, the protonated histamine cations worked as bridge to link alternately with [Bi_2I_(10)]^(4-) anion by hydrogen bonds to form organic-inorganic hybrid 1D chains. In addition, compound 1 emitted a green light at the excitation wavelength of 400 nm and the maximum emission wavelength is at 503 nm.展开更多
