摘 要: | (E)-2,6-Dimethyl-4-styrylpyridine-3,5-dicarboxylic acid (H2mspda) is firstly employed in coordination chemistry.Two isostructural two-dimensional (2-D) 4-connected metal-organic coordination polymers with a general formula of {M2(mspda)2(bpy)(H2O)2]}n (M=Zn(1) and Co(2)) are assembled from H2mspda,4,4'-bipyridyl (bpy),zinc and cobalt ions under hydrothermal conditions,and characterized by single-crystal X-ray diffraction analyses.Complex 1 crystallizes in monoclinic,space group P21/n with a=14.551(4),b=10.941(3),c=14.945(4),β=98.817(4)o,V=2351.3(1)3,Dc=1.511 g/cm3,μ(MoKα)=1.090 mm-1,F(000)=1104,Z=4,the final R=0.0335 and wR=0.0485 for 3296 observed reflections (I 2σ(I)).In compound 1,mspda2-spacers are only arrayed in a head-to-tail fashion which corresponds to a 2-D coordination polymer.Solid-state H2mspda and complex 1 have expected photoluminescence (λem=475~496 nm) at room temperature.
