摘 要: | Under hydrothermal conditions, the reactions of Ni~Ⅱ/Cu~Ⅱ ions with 3-(6-aminpyridinium-3-yl) benzoate(HL) afford two compounds [NiL 2]n(1) and [Cu L2(H2 O)]n(2). On the basis of X-ray diffraction analysis of the two compounds, the results show that compound 1 features one-dimensional(1 D) double-strand coordination arrays, while 2 presents the 63-hcb layers. Both compounds are further constructed into a 3 D supramolecular structure with the aid of weak secondary interactions. Thermal stabilities and magnetic properties of compounds 1 and 2 were also investigated.
