Abstract
- In this paper, two novel metal-organic frameworks [Cu(bna1)(DMF)]n·nH2O·nCH3OH (complex1) (H2bna1= 2,2′-dihydroxy-1,1′-dinaphthyl-6,6′-dicarboxy acid) and [Co(bna2)2(bpy)(H2O)2]n(complex2) (H2bna2= 2,2′-dihydroxy-1,1′-Dinaphthyl-4,4′-dicar–boxyacid) have been synthesized under mild conditions and carefully characterized. Crystal structural analysis reveals that complex1adopts a 1D infinite chain structure, which forms 2D sheet by π–π weak interactions. Complex2possesses 2D sheet structure, where Cobalt ions are recognized as the nodes. So it generated a regular two-dimensional grid with the size of 1.57 × 1.15 nm. Complex2assembles into a 3D supramolecular network connected by the hydrogen bonds. IR spectra studies indicate that the coordination mode of carboxyl group of complex1and complex2are chelating with the metal ions. X-ray powder diffraction (PXRD) studies of both complexes confirm that there is no impurity phase in both complexes since their diffraction patterns match well with the simulated ones.
