摘要
Two new supramolecular complexes [MnL（H2O） 4]（1） and [ZnL（H2O） 5]·0.25H2O（2） （H2L = 5-carboxy-1-carboxymethyl-2-oxidopyridinium） have been synthesized and structurally characterized by elemental analysis,IR and X-ray single-crystal structure determination. Complex 1 crystallizes in the monoclinic system,space group P21/n with a = 5.1537（2） ,b = 21.2008（9） ,c = 10.9727（4）A,β = 99.182（2） °,V = 1183.54（8）A^3,C8H13MnNO9,Mr = 322.13,Dc = 1.808,Z = 4,F（000） = 660,μ = 1.160,R = 0.0372 and wR = 0.0750 for 2217 observed reflections（I 〉 2σ（I）） . Complex 2 crystallizes in the triclinic system,space group P1^- with a = 7.730（2） ,b = 8.030（2） ,c = 11.400（2） A^3,α = 104.27（3） ,β = 92.93（3） ,γ = 102.67（3） °,V = 664.9（2） 3,C8H15.5ZnNO10.25,Mr = 355.08,Dc = 1.774,Z = 2,F（000） = 365,μ = 1.899,R = 0.0243 and wR = 0.0695 for 2759 observed reflections（I 〉 2σ（I）） . Their thermal properties have been studied.
