(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.

Two isostructural two-dimensional (2-D) 4-connected metal-organic coordination polymers with a The general formula of {M 2 [(mspda) 2 (bpy) (H 2 O) 2]} n (M═Zn (1) and Co (2)) are assembled from H2mspda, 4,4’-bipyridyl (bpy) crystallinity in monoclinic, space group P21 / n with a = 14.551 (4), b = 10.941 (3), c = 14.945 (4) Final, 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, = 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. H2mspda and complex 1 have expected photoluminescence (λem = 475 ~ 496 nm) at room temperature.
