Abstract
A series of metal coordination polymers, [Co 2(NB) 4(bpp) 2(H 2O)]H 2O (1), [Co 2(e,e-trans-chdc)(e,a-cischdc)(bpp) 2] (2), [Ni(e,e-trans-chdc)(bpp)(H 2O) 2] (3), [Ni 2(PDA) 2(bpp) 2(H 2O) 3]·H 2O (4), and [Ni-(mBDC)(bpp)] (5) (NB = 3-nitrobenzoate anion; bpp = 4,4'-trimethylene dipyridine; chdc = cyclohexane-1,4-dicarboxylate anion; PDA = 1,4-phenylenediacetate anion; mBDC = 1,3-benzene dicarboxylate anion), were synthesized from metal ions and organic mixed-ligands by hydrothermal reactions. The single crystal structure analysis revealed that 1, 3, and 4 were 2D sheets with bilayer (1 and 4) and 2-fold interpenetrated layers (3), 2 is a 3D binodal (4,5)-connected framework, and 5 is a 1D chains. The non-covalent interactions of H-bonds and π-π stacking caused this conformation of highly cross-linked networks. Compounds 1-5 were further characterized by thermal gravimetric analysis, powder X-ray diffraction, UV-vis, infrared, and PL spectroscopy.
