摘要采用水热法合成了Ni(c8h6 no2) 2 (h2o) 2(1)、Co(c8h6 no2) 2(2)和Cu(c8h6 no2) 2 (h2o) 2(3)三个金属有机聚合物网络。单晶x射线分析表明，在这些化合物中，金属中心通过反式-4-吡啶丙烯酸酯配体连接，形成互穿的无限网络。Ni（II）和Cu（II）化合物具有互穿的方形网格层覆盖层，而Co（II）化合物具有互穿的菱形网络。通过比较这三种化合物，可以利用金属的配位特性在互穿网络中形成潜在的客体分子包涵的空腔。用单晶x射线衍射法测定了三种化合物的晶体结构，并用直接法求解。晶体数据为1：正交，空间群Pbcn， a =13.735(3) a, b =6.995(2) a, c =16.723(3) a, V =1606.7(6) a3, Z =4，最终细化（I >2 σ (I)）： r1 =0.0296, w r2 =0.0843。晶体数据2：单斜晶，空间群Cc， a =11.5717(9) a, b= 21.2838(16) a, c =8.5504(7) a, β =130.5210（10）°，V =1600.8(2) a 3, Z =4，最终细化（I >2 σ (I)）： r1 =0.0347, w r2 =0.0879。晶体数据为3：正交，空间群Pbcn， a =13.6844(13) a, b =7.5053(8) a, c =15.929(4) a, V =1636.0(5) a 3, Z =4，最终细化（I >2 σ (I)）， r1 =0.0299, w r2 =0.0787。
Abstract Three metal–organic polymeric networks, Ni(C 8 H 6 NO 2 ) 2 (H 2 O) 2 (1), Co(C 8 H 6 NO 2 ) 2 (2), and Cu(C 8 H 6 NO 2 ) 2 (H 2 O) 2 (3), were synthesized by the hydrothermal method. Single-crystal X-ray analysis revealed that within these compounds metal centers are linked through trans -4-pyridylacrylate ligands to form interpenetrating infinite networks. The Ni(II) and Cu(II) compounds possess an overlay of interpenetrating square grid layers, whereas the Co(II) compound possesses interpenetrating diamondoid networks. Comparing these three compounds, the formation of cavities potentially for guest molecule inclusion within the interpenetrating networks could be achieved by taking advantage of the coordination nature of metals. Crystal structures of all three compounds were determined by single-crystal X-ray diffraction methods and solved by direct method.
