Resumo

The electronic, adsorption and structural properties of a layered coordination polymer (CP), [{[}Cu(3,4-pvb)(2)]center dot x(dmf)center dot y(H2O)](n) (x = 4; y = 0 or x = 3.5; y = 1), formed by the coordination of [3-{[}2-(4-pyridyl)vinyl]]benzoate (3,4-pvb(-)) to copper(ii), were studied both experimentally and computationally. Most of the CP structure is held together due to a non-covalent interaction of pi-stacking resemblance, which together with the metal coordination arranged itself as a two-dimensional framework with large diamond shape channels that extends in a corrugated fashion. The stacking of the corrugated layers leads to a three-dimensional supramolecular structure with an estimated surface area of 26.5 m(2) g(-1) and large rhombus pores with a volume of about 0.09 cm(3) g(-1). Each rhombus pore is filled with a supramolecular chain of dmf molecules extending along the crystallographic a-axis. The results indicated that the 3,4-pvb(-) ligand, along with the solvent induced template effect, leads to a distinct structural topology compared to other pyridylvinyl(benzoate) based CPs. (AU)
