| 英文摘要 | six complexes, rubidium and cesium 3,5-dinitropyrid-2-onate (2dnpo), 3,5-dinitropyrid-4-onate (4ndpo), 3,5-dinitropyrid-4-one-n-hydroxylate (4dnpno), were synthesized and characterized by elemental analysis, ft-ir, tg-dtg and x-ray single-crystal diffraction analysis. all the complexes crystallized from water and one of them was a hydrate. rubidium 3,5-dinitropyrid-4-one-n-hydroxylate was crystallized with the 1 : 2 stoichiometry as rb[h(4dnpno)(2)] upon absorption of carbon dioxide. the structural determinations showed that the coordination sphere around a metal centre is made up of oxygen atoms and nitrogen atoms, except for the 4dnpno complexes, where the coordination sphere accommodates exclusively oxygen atoms. the coordination numbers of the metal centers vary from 8, 10, 11 to 12, while the ligands, each employing its pyridone tautomer, link with metal cations. bridging oxygen atoms play an important role in construction of two- and/or three-dimensional networks of these complexes. hydrogen bonding contributes to the connectivity within a given sheet in rb[h(4dnpno)(2)]; aromatic - stacking interactions exist only in cs(4dnpno). the interactions between metal atoms and ligands are generally very weak. the organization of all layer structures appears to be governed mainly by steric effects and electrostatic forces with very little directional influence of the cations. the thermogravimetric analyses of these complexes showed the following consecutive processes: loss of no(2) groups, collapse of the pyridyl ring backbones and finally inorganic residue formation. these complexes could be used as probes in template effects of heavy alkali-metal cations in the organization of biorelevant ligands and as environment-friendly energetic catalysts in solid propellants. |
