Hydrothermal Synthesis and Crystal Structure of One 3D Coordination Polymer of Nickel(Ⅱ) Achieved from 5-Iodo-isophthalic Acid Ligand
摘要:
A new coordination polymer [Ni(L)(m-bix)(H2O)]n (1, H2L=5-iodo-isophthalic acid, m-bix=1,3-bis(imidazol-1-ylmethyl)-benzene) has been synthesized by the hydrothermal method and characterized by IR, elemental analysis, powder XRD and single-crystal X-ray analysis. The crystal is of triclinic, space group P1 with a=9.1638(3), b=10.2319(3), c=13.2463(4) Å, α=80.1710(10), β=83.671(2), γ=70.3790(10)°, C22H19NiIN4O5, Mr=605.02, V=1150.85(6) Å3, Dc=1.746 g/cm3, F(000)=600, μ=2.225 mm-1, S=1.045 and Z=2. The final R=0.0388 and wR=0.1257 for 5089 observed reflections with I>2σ(I). In the title complex, the M and P layers are arranged alternately to give a double-layer structure by the symmetry related hydrogen bonds, and these double-layers are further joined together to achieve a 2D supramolecular architecture through I…π interaction involving iodine atoms and imidazole rings. The thermal stability of the title complex was studied by thermal gravimetric (TG) and differential thermal analysis (DTA).
