Base on ligands 5-aminonicotinic acid and 5-aminoisophthalic acid, three novel d(10) coordination polymers [Zn(ant)(2)](n) (Zn-ant) (ant = 5-aminonicotinate anion), [CdBa(aip)(2)(H2O)(2)](n) (CdBa-aip) and [Cd-3(aip)(2)(C2O4)(H2O)(6)](n) (Cd-aipox) (aip = 5-aminoisophthalate anion) are obtained by hydrothermal reactions, and characterized by means of FT-IR spectra, elemental analysis, single-crystal X-ray diffraction analysis and X-ray powder diffraction techniques. Thermogravimetric analysis is also carried out in order to investigate the stability of compounds Compound Zn-ant exhibits a 2D interlaced-bilayer structure. While compounds CdBa-aip and Cd-aipox feature the unusual 2D pillared-bilayer structures formed by the cross-linking of the aip and oxalate units. Considering the complicated hydrogen bonds and interlayer pi...pi stacking interactions, all of the three compounds are finally packed into three-dimensional supramolecular networks. The deprotonating reagent-induced effect is responsible for the generation of two different compounds CdBa-aip and Cd-aipox. In addition, the photoluminescent properties of three compounds have also been investigated in the solid state at room temperature. (C) 2016 Elsevier B.V. All rights reserved.
