摘　　要：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） A, β = 132.5620（10）°, V = 3708.5（11） A^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（H） 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=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） A, β = 132.5620（10）°, V = 3708.5（11） A^3, the final R = 0.0349 and wR = 0.0914 for 3424 independent reflections with Rint = 0.0214.
