在温和条件下合成了二维层网结构的无机－有机杂化晶体Zn(BDC)(C_3H_3N_2) ·(DMF)(1)和Co_2(BDC)_2(C_5H_5N)_4·2(DMF)·(C_5H_5N)·(C_5H_5N) (2)，并 通过ICP和X射线单晶衍射分析等手段对其结构进行了表征。1的晶胞数据：C_(14) H_(14)N_3O_5Zn, M_r = 369.65，单斜晶系，C2/c空间群，晶胞参数a = 2.1059 (4) nm, c = 1.4836(3) nm, β = 99.09(3)°，V = 3.1826(11) nm~3, Z = 4, D_X = 1.543 Mg/m~3, μ = 1.571 mm~(-1), F(000) = 1512。最后的一致性因子 为R = 0.0697, R_w = 0.2018。2的晶胞数据：C_(47)H_(47)N_7O_(10)Co_2, M_r = 987.78，单斜晶系，P2(1)/n空间群，晶胞参数a = 1.0829(2) nm, b = 1. 5431(3) nm, c = 1.4428(3) nm, β = 101.65(3)°，V = 2.3612(8) nm~3, Z = 2, D_X = 1.391 Mg/m~3, μ = 0.767 mm~(-1), F(000) = 1024。最后的一致性 因子为R = nm, β = 101.65(3)°, V = 2.3612(8) nm~3, Z = 2, D_X = 1.391 Mg/m~3, μ = 0.767 mm~(-1), F(000) = 1024。最后的一致性因子为R = 0. 0652，R_w = 0.1888。1和2的结构都是由无机簇M_2(CO_2)_4(M = Zn, Co)通过苯 环连接而形成的层网结构。它们都存在由4个无机簇与4个苯环形成的环，其大小约 为0.9 nm * 0.9 nm。由于咪唑和吡啶分别与1和2无机簇的两极配位，阻止了它们 形成三维骨架结构。

Two 2-D inorganic-organic hybrid layered network materials Zn(BDG) (C_3H_3N_2)·(DMF) (1) and Go_2-(BDG)_2(C_5H_5N)_4·2(DMF)(C_5H_5N)(2) were synthesized under mild synthesis condition. Their crystal structures were determined by using single crystal X-ray diffraction. Crystal structures were solved by direct method and refined by fullmatrix least-square method. Compound 1 is monoclinic, space group C2/c with a = 2.1059(4) nm, b = 1.0316(2) nm, c = 1.4836(3) ran, β = 99.09(3)°, F = 3.1826(11) nm3, Z = 4, Dx = 1.543 Mg/m~3, C_(14)H_(14) N_3O_5Zn, Mr = 369.65, μ = 1.571 mm~(-1), F(000) = 1512, R =0.0697, R_W = 0.2018, and compounds is monoclinic, space group P2(l)/n with a = 1.0829(2) nm, 6 = 1.5431(3) ran, c = 1.4428(3) nm, β= 101.65(3)°, V = 2.3612(8) nm~3, Z = 2, D_x = 1.391 Mg/m~3, C_(47)H_(47)N_7O_(10) Co_2, M_r = 987.78, μ =0.767 mm~(-1), F(000) = 1024, 72 = 0.0652, R_W = 0.1888. They are layered networks with 0.9 nm*0.9 nm pore.
