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.
