Two new one-dimensional coordination polymers,[Zn(L)(phen)]n 1 and {[Co2(L)2(phen)2]·2H2O}n 2(H2L=5-methoxyisophthalic acid,phen=1,10-phenanthroline),have been obtained by hydrothermal conditions.According to their single-crystal X-ray diffraction analyses,complex 1 crystallizes in the monoclinic system,space group P2/c with a=8.9195(11),b=12.3620(15),c=17.0211(18),β=106.690(5)o,V=1797.7(4)3,the final R=0.0298 and wR=0.0715 for 3351 independent reflections with Rint=0.0353.Complex 2 crystallizes in the monoclinic system,space group C2/c with a=24.981(4),b=11.1204(19),c=18.125(3),β=132.5620(10)o,V=3708.5(11)3,the final R=0.0349 and wR=0.0914 for 3424 independent reflections with Rint=0.0214.Both 1 and 2 show L-bridged one-dimensional chain.1 and 2 are further assembled by π-π and hydrogen bonding interactions into 2-D layer structures,and they also display 3-D supramolecular frameworks through their other hydrogen bonds.Zn(Ⅱ) ion is five-coordinated with a distorted trigonal bipyramidal coordination geometry,while Co(Ⅱ) ion is six-coordinated and resides in a distorted octahedral coordination geometry.Additionally,complex 1 shows fluorescence in the solid state at room temperature.
Two new one-dimensional coordination polymers [Zn (L) (phen)] n 1 and {[Co2 (L) 2 (phen) 2] · 2H2O} n 2 (H2L = 5-methoxyisophthalic acid, phen = -phenanthroline, have been obtained by hydrothermal conditions. According to their single-crystal X-ray analysis, complex 1 crystallizes in the monoclinic system with space group P2 / c with a = 8.9195 (11), b = 12.3620 , β = 106.690 (5) o, V = 1797.7 (4) 3, the final R = 0.0298 and wR = 0.0715 for 3351 independent reflections with Rint = 0.0353.Complex 2 crystallizes in the monoclinic space group C2 / c with a = 24.981 (4), b = 11.1204 (19), c = 18.125 (3) β, β = 132.5620 (10) o, V = 3708.5 = 0.0349 and wR = 0.0914 for 3424 independent reflections with Rint = 0.0214. Both 1 and 2 show L-bridged one-dimensional chain. 1 and 2 are further assembled by π-π and hydrogen bonding interactions into 2-D layer structures, and they also display 3-D supramolecular frameworks through their other hydrogen bonds.Zn (Ⅱ) ion is five-coordinated with a distorted t rigonal bipyramidal coordination geometry, while Co (II) ion is six-coordinated and resides in a distorted octahedral coordination geometry. Additionally, complex 1 shows fluorescence in the solid state at room temperature.
