Synthesis and Crystal Structure of an Adipate-bridged Dinuclear Cadmium(Ⅱ)Polymer with 2-Methylpyrazino[2,3-f][1,10]-phenanthroline(mpphen)Terminal Ligands

<正>A metal-organic coordination polymer,Cd(C_(15)H_(10)N_4)(C_6H_8O_4)]_(2n)(1,C_(15)H_(10)N_4: 2-methyl-pyrazino-2,3-f]1,10]-phenanthroline(mpphen),C_6H_8O_4:adipate),was synthesized via hydrothermal synthesis.The polymer was characterized by elemental analysis,IR,TG and single-crystal X-ray diffraction.X-ray diffraction shows that 1 is a cadmium polymer constructed by adipate-bridged dinuclear clusters,and each adipate connects two clusters to form a two-dimensional planar structure.Crystal data for 1:monoclinic,space group C2/c,a=22.403(9),b= 16.039(6),c=13.808(6)(?),β=125.262(6)°,V=4051(3)(?)~3,M_r=502.79,D_c=1.649g/cm~3,μ(MoKα)=1.114 mm~(-1),F(000)=2016,Z=8,the final R=0.0509 and wR=0.1054 for 1509 observed reflections(I2σ(I)).
