Four new Zn(ii) and Cd(ii) coordination polymers using two amide-like aromatic multi-carboxylate ligands: synthesis, structures and lithium-selenium batteries application.

ABSTRACT: Four new coordination polymers, {[Zn(3-PBI)(H₂O)]·2DMF} _n (1), [Cd(3-PBI)(DMF)] _n (2), {[Zn₄(μ₄-O)(4-PBI)₃]·3DMF} _n (3), {[Cd₄(4-PBI)₄(H₂O)₆]·13H₂O} _n (4), have been constructed from two isomeric flexible multi-carboxylate ligands, 3-H₂PBI = 5-(3-(pyridin-3-yl)benzamido)isophthalic acid and 4-H₂PBI = 5-(3-(pyridin-4-yl)benzamido)isophthalic acid. Structural analysis reveals that compound 1 is a one-dimensional (1D) ladder-like chain assembled by Zn(ii) ions and 3-PBI^2- ligands, which further extend into a 3D supramolecular structure through π⋯π stacking and interlayer (O-H⋯O) hydrogen bond
