| Abstract: A new metal-organic coordination polymer [Ni(NIPH)(bix)(H2O)2]n (1, H2NIPH=5-nitroisophthalic acid, bix=1,4-bis(imidazol-1-ylmethyl)-benzene) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, TG, UV and single-crystal X-ray diffraction. The title compound crystallizes in the orthor-hombic system, space group Pnma with a=1.743 62(8) nm, b=2.128 96(9) nm, c=0.568 59(3) nm, V=2.110 66(17) nm3, C22H21N5NiO8, Mr=542.15, Dc=1.706 g·cm-3, μ(Mo Kα)=0.984 mm-1, F(000)=1 120, Z=4, the final R=0.032 4 and wR=0.819 for 1 703 observed reflections (I>2σ(I)). It exhibits a one-dimensional chain-like structure. CCDC: 857178. |
