Syntheses, structures, and photoluminescence of a series of d10 coordination complexes from N,N′-bidentate imidazo[4,5-f][1,10]phenanthroline and benzene-1,3,5-tricarboxylic acid
摘要:
Four new d(10) metal-organic complexes, [Cd(L)(HBTC)(H2O)](n) (1), [Cd2Cl(L)(2)(BTC)(H2O)(2)](n) (2), [Zn(L)(HBTC)(H2O)(2)](2)center dot 2H(2)O (3) and [Zn(L)(HBTC)(H2O)](n) (4) were prepared through hydrothermal reactions of L and H3BTC (L = imidazo[4,5-f][1,10] phenanthroline and H3BTC = benzene-1,3,5-tricarboxylicacid). These complexes were structurally characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. Complexes 1 and 4 are analogous, showing 2D network with the Schlafli symbol of 4.8(2), which further linked into 3D supramolecular architecture by aromatic pi-pi interactions. Complex 2 possesses a 1D chain structure. Two neighboring chains of 2 are linked through the pi-pi interactions into a double chain supramolecular structure. Complex 3 features a dinuclear structure and further forms a 2D layer by pi-pi interactions. The thermal stabilities and photoluminescent properties of the coordination compounds have also been investigated. (C) 2012 Elsevier B.V. All rights reserved.
