| Abstract: Two coordination polymers [2{Ni(HO-BDC)(bpe)H2O}]n·n(py)·nH2O and [Ni(HO-BDC)(bipy)]n·nH2O (where HO-H2BDC=5-Hydroxyisophthalic acid, bpe=1,2-bis(4-pyridyl)ethane，bipy is bipydine and py is pyridine) have been synthesized and characterized by elemental analysis, IR spectroscopy, and the crystal structure was determined by X-ray diffraction technique. The polymer 1 belongs to triclinic, space group P1, with a=1.019 2(2) nm, b=1.145 5(3) nm, c=1.246 0(3) nm, α=68.377(5)°, β=67.275(12)°, γ=71.821(7)°, V=1.222 7(5) nm3, Z=1, Mr=979.26, Dc=1.330 g·cm-3, F(000)=508, μ=0.835, the final R1=0.049 4 and wR2=0.112 1 for 3400 observed reflections with I＞2σ(I). The crystal 2 belongs to monoclinic, space group P2/c, with a=0.861 1(2) nm, b=1.106 8(3) nm, c=1.839 4(4) nm, β=104.267(9)°, V=1.699 0(7) nm3, Z=4, Mr=413.00, Dc=1.615 g·cm-3, F(000)=848, μ=1.182, the final R1=0.063 5 and wR2=0.196 9 for 2290 observed reflections with I＞2σ(I). The structural analysis shows that the two complexes have a three-dimensional structure network by hydrogen bonding interactions. CCDC: 626599,1; 638568, 2. | |
