| Popis: | The d10 coordination polymers (CPs), [Zn(L1)(OH)]n (1) and [Cd(L2)2]n (2) were obtained from isomeric ligands 3-(6-aminpyridinium-3-yl) benzoic acid (L1) and 4-(6-aminpyridinium-3-yl) benzoic acid (L2), and characterized by elemental analyses, IR spectroscopy, single-crystal and powder X-ray diffraction. In compound 1, a spiral chain structure connected by μ2-OH– and the ZnII ions, which are further linked by the L1 ligands to give atwo-dimensional layered structure. Classical hydrogen-bonding interactions (O···H–N) between adjacent layers result in three-dimensional supramolecular structure. Compound 2 features a three-dimensional framework formed by linking [Cd2(COO)2] clusters in a bcu net. Thermal stabilities and fluorescent properties of 1 and 2 were also investigated. |
