A series of new 1D chain and 2D coordination polymers with cyclotriguaiacylene-type ligands are reported. A zig-zag 1D coordination chain is found in complex [Cd(2)(4ph4py)(NO(3))(3)(H(2)O)(2)(DMA)(2)]·(NO(3))·(DMA)(4), where 4ph4py = tris[4-(4-pyridyl)benzoyl]-cyclotriguaiacylene and DMA = dimethylacetamide, while complex [Zn(4ph4py)(2)(CF(3)COO)(H(2)O)]·(CF(3)COO)(NMP)(7), where NMP = N-methylpyrrolidone, has a doubly bridged coordination chain structure. Complexes [M(3ph3py)(NO(3))(2)]·(NMP)(4) where M = Co or Zn, 3ph3py = tris[3-(3-pyridyl)benzoyl]cyclotriguaiacylene, are isostructural and feature 1D ladder coordination chains. Complexes [Cd(2)(4ph4py)(2)(NO(3))(4)(NMP)]·(NMP)(9)(H(2)O)(4) and [Co(4ph4py)(H(2)O)(2)]·(NO(3))(2)·(DMF)(2), where DMF = dimethylformamide, both have (3,4)-connected 2D coordination polymers with a rare (4(2).6(2))(4.6(2))(2) topology. A 2D coordination polymer with this topology is also found in complex [Co(2)(3ph4py)(2)(NO(3))(H(2)O)(5)]·(NO(3))(3)·(DMF)(9) where 3ph4py = tris[3-(4-pyridyl)benzoyl]cyclotriguaiacylene. All 2D coordination polymer complexes are interpenetrating or polycatenating. Co(2)(3ph4py)(2)(NO(3))(H(2)O)(5)polymers form a 2D→3D polycatenation showing self-complementary "hand-shake" interactions between the host-type ligands.
报道了一系列具有环三并[g,i,l]苝型配体的一维链和二维配位聚合物。在配合物[Cd(2)(4ph4py)(NO(3))(3)(H(2)O)(2)(DMA)(2)]·(NO(3))·(DMA)(4)中发现了一个锯齿形的一维配位链，其中 4ph4py = 三[4-(4-吡啶基)苯甲酰基]-环三并[g,i,l]苝，而 DMA = 二甲基乙酰胺，而配合物[Zn(4ph4py)(2)(CF(3)COO)(H(2)O)]·(CF(3)COO)(NMP)(7)，其中 NMP = N-甲基吡咯烷酮，具有双桥接配位链结构。配合物[M(3ph3py)(NO(3))(2)]·(NMP)(4)，其中 M = Co 或 Zn，3ph3py = 三[3-(3-吡啶基)苯甲酰基]环三并[g,i,l]苝，是同构的，具有一维梯形配位链。配合物[Cd(2)(4ph4py)(2)(NO(3))(4)(NMP)]·(NMP)(9)(H(2)O)(4)和[Co(4ph4py)(H(2)O)(2)]·(NO(3))(2)·(DMF)(2)，其中 DMF = 二甲基甲酰胺，均具有罕见的(4(2).6(2))(4.6(2))(2)拓扑结构的(3,4)-连接的二维配位聚合物。在配合物[Co(2)(3ph4py)(2)(NO(3))(H(2)O)(5)]·(NO(3))(3)·(DMF)(9)中也发现了具有这种拓扑结构的二维配位聚合物，其中 3ph4py = 三[3-(4-吡啶基)苯甲酰基]环三并[g,i,l]苝。所有二维配位聚合物配合物都是互穿或多链的。Co(2)(3ph4py)(2)(NO(3))(H(2)O)(5)聚合物形成二维→三维多链，显示出主体型配体之间的自互补“握手”相互作用。
