| Abstract | By using isomeric N,N'-di(2-pyridyl)-adipoamide (L-1), N,N'-di(3-pyridyl)adipoamide (L-2) and N,N'-di(4-pyridyl)adipoamide (L-3) and isomeric 1,2- benzenedicarboxylic acid (1,2-H2BDC), 1,3-benzenedicarboxylic acid (1,3-H2BDC) and 1,4- benzenedicarboxylic acid (1,4-H2BDC), eight Zn(II) and Cd(II) coordination polymers [Zn(1,2-BDC) (L-2)(infinity), 1; [Zn-2(1,3-BDC)(2)(L-2)(H2O)(2)](infinity), 2; [Zn-2(1,4-BDC)(2) (L-1)(H2O) (2)](infinity), 3; {[Zn-2 (1,2-BDC)(2)(L-3)(H2O)(2)]center dot 2H(2)O}(infinity), 4; {[Cd(1,2- BDC)(L-2)(H2O)]center dot H2O}(infinity), 5; [Cd-2(1,3-BDC)(2)(L-2)(H2O)(4)](infinity), 6; {[Cd- 2(1,4-BDC)(2)(L-2)(2)]center dot(H2O)(3)}(infinity), 7; [Cd-2(1,4-BDC)(2)(L-1)(H2O)(2)] (infinity), 8, have been synthesized under hydrothermal conditions. Complexes 1, 4, and 5 form 11) double-looped chain, 11) chain with loops and 2D layer with loops, respectively, and complex 6 exhibits a 1D ladder chain. Complex 2 shows rare 3-fold interpenetrated hcb layers, in which each layer interdigitates with other four parallel layers by directing the 1,3-BDC ligands into the windows of the adjacent nets, whereas complexes 3 and 8 forms planar and undulated hcb layers, respectively. Complex 7 shows a 3D self-penetrating net of {4(24).5.6(3)}-ilc topology with a unique arrangement for the L-2 spacer ligands. The L-1 ligands in complexes 3 and 8 adopt the new tetradentate bonding mode involving chelation and bridge through two pyridyl nitrogen atoms and two amide oxygen atoms, whereas the L-2 and L-3 ligands in other complexes show the bidentate bonding mode through the two pyridyl nitrogen atoms. The various bonding modes and the ligand-isomerism of the spacer ligands BDC2- and L-1-L-3 as well as the identity of the metal center play important roles in determining the structural diversity. |
