The crystal belongs to a monoclinic system with space group P2_1/n, a=0.64718(13) nm, b=2.6738(6) nm, c=1.0423(2) nm, β=106.384(3)°, Z=4, V=1.730(3) nm^3, D_c=2.163 g/cm^3, μ=10.682 mm^(-1), F(000)=1072, R=0.0329, wR=0.0659. The structure shows a distorted pentagonal bipyramidal configuration with the seven-coordinated central Bi atom. In the crystal, the molecular packing in the unit cell reveals that the two adjacent molecules are symmetrically linked each other in the dimer by virtue of a couple of Bi-S interaction.展开更多
A bismuth（Ⅲ） complex 1 （H2-4,4＇-bipy）[Bi（HPPA）5]（H2PPA）.4H2O （H2PPA = p- hydroxy- phenylacetic acid, 4,4＇-bipy = 4,4＂-bipyridyl） was hydrothermally synthesized from p-hydroxy-phenylacetic acid （H2PPA）,...A bismuth（Ⅲ） complex 1 （H2-4,4＇-bipy）[Bi（HPPA）5]（H2PPA）.4H2O （H2PPA = p- hydroxy- phenylacetic acid, 4,4＇-bipy = 4,4＂-bipyridyl） was hydrothermally synthesized from p-hydroxy-phenylacetic acid （H2PPA）, Bi（NO3）3＂6H20 and 4,4＇-bipyridyl, and characterized by elemental analysis, IR, molar conductivity and TG. The single-crystal X-ray diffraction studies demonstrated that the complex is of monoclinic system, space group P21 with a = 10.928（7）, b = 22.558（7）, c = 11.313（7） A, β = 91.864（4）°, V = 2787.7（4） A3, Z = 2, C58H61BiN2O22, Mr = 1347.07, F（000） = 1364, Dc= 1.605 g/cm-3, p（MoKa） = 3.247 mm-1, the final R = 0.0269 and wR = 0.0540 for 9776 observed reflections with I 〉 2or（I）. The bismuth（I/I） is seven-coordinated with O atoms, forming a monocapped octahedral geometry. Complex 1 further forms a 3D supramolecular architecture by hydrogen bonds and π-π stacking interactions. Moreover, the interaction between the complex and DNA was studied by EtBr fluoescent probe.展开更多
