Modulated assembly of interdigitated 1D isolated tube and 2D highly undulating layer based on N-donor ligand and multidentate carboxylic acid

Two coordination polymers, {[Zn(Hpdcd)(bbi)](DMSO)(2H2O)]}n (1) and {[Ni(Hpdcd)(bbi)·H2O]2H2O}n (2) (H3pdcd = 1-(4-carboxyphenyl)-2,5-dimethyl, 1H-pyrrole-3,4-dicarboxylic acid, bbi = 1,1′-(1,4-butanediyl)bis(imidazole)), have been solvothermally synthesized. 1 shows a 1D isolated tube with a 1D→2D interdigital structure, while 2 exhibits a 2D deeply corrugated layer with a novel (2D→3D) interdigitated architecture.

The metal ion is first connected by bbi ligand to form metallocycle or meso-helical chain as the subunits, which were further bridged by the partly deprotonated Hpdcd2 − ligands to generate a 1D isolated tube and 2D highly undulating layer, respectively.Figure optionsDownload as PowerPoint slideHighlights
► 1D isolated tube and 2D highly undulating layer were prepared by bbi and H3pdcd.
► Compounds 1 and 2 show a 1D→2D and 2D→3D interdigital structure, respectively.
► The luminescent property of 1 has been investigated.
