基于6-甲基吡啶-2，4-二甲酸N-氧化物（MPDCO）配体[M（MPDCO）（H2O）x]n的八种新型配位聚合物（M = Mn ~（2+），x = 1（1）; M = Cu2+，x = 2（2）），[M（MPDCO）（bpy）（H2O）·（H2O）]n（M = Co2+（3），Ni2+（4）），[M（MPDCO）（TPB）0.5（H2O）·（H2O）x]n（M = Co2+（5），Ni2+（6），Zn2+（7），Cd2+（8））（bpy = 4，4 ′-联吡啶，TPB = 1，2，3，4-四（4-吡啶基）丁烷）的合成和结构表征。化合物1和2都是二维层，它们通过强的层间氢键相互作用进一步堆叠形成三维超分子结构。化合物3和4含有3重互穿网络，是同构的并且具有3-D（10，3）-d开放骨架。在同晶化合物5-8中，金属阳离子、MPDCO和四配体1，2，3，4-四（4-吡啶基）丁烷（TPB）构成了具有（42·62·82）（4·62）2拓扑结构的非等价节点的二维片层.然后，这些二维片的倾斜相互渗透导致三维多孔电弧。
Eight novel coordination polymers based on the 6-methylpyridine-2,4-dicarboxylic acid N-oxide (MPDCO) ligand, [M(MPDCO)(H2O)x]n (M = Mn2+, x = 1 (1); M = Cu2+, x = 2 (2)), [M(MPDCO)(bpy)(H2O)·(H2O)]n (M = Co2+ (3), Ni2+ (4)), [M(MPDCO)(TPB)0.5(H2O)·(H2O)x]n (M = Co2+(5), Ni2+ (6), Zn2+ (7), Cd2+ (8)) (bpy = 4,4′-bipyridine, TPB = 1,2,3,4-tetra-(4-pyridyl)-butane) have been prepared and structurally characterized. Compounds 1 and 2 are both two-dimensional (2-D) layers, which are further stacked via strong interlayer hydrogen-bond interactions to form three-dimensional (3-D) supramolecular structures. Compounds 3 and 4, which contain 3-fold interpenetrating nets, are isostructural and feature 3-D (10,3)-d open frameworks. In isomorphous compounds 5–8, 2-D sheets with nonequivalent nodes of (42·62·82)(4·62)2 topology were constructed from metal cations, MPDCO, and the four-connecting ligand 1,2,3,4-tetra-(4-pyridyl)-butane (TPB). Then the inclined interpenetration of these 2-D sheets leads to 3-D porous arc...
