•NH⋯N and NH⋯O hydrogen-bonding recognition•Self-assembly•Dumbbell-shape coordinated building block•Tripodal•Tunable by the length of spacers
Three hydrogen-bonding frameworks based on NH⋯N and NH⋯O Hbond linkages have been synthesized and structurally characterized by using ntb (tris(2-benzimidazoylmethyl)amine) to react with two Cd(II) salts in the presence of dysfunctional bridging spacers of NaN3, 4'4-bipy and H2tpa (terephthalic acid) respectively. The building blocks of three complexes exhibit dumbbell-shape which stacks each other in the lattice leading to three 3D hydrogen-bonding frameworks with diversiform topology net of distorted NaCl net, (4,4) layer and 424 · 64 net.
Graphical abstractThree hydrogen-bonding frameworks have been synthesized via assembly of dumbbell-shape building units which were tunable by the length of spacers. The inerrant NH⋯N and N-H⋯O hydrogen-bonding recognition between ntb and the counter anions is responsible for the assembly of dumbbell-shape coordinated building block.Figure optionsDownload full-size imageDownload as PowerPoint slide
