Abstract:
The hydrothermal reactions of divalent metal salts with 4-HOOC-C6H4-CH2-NH2CH2PO3H2 (H3L) led to four Metal-organic phosphonates (MOPs), namely, Ni(HL)(H2O)(2) (1), Cd(HL) (2), CdCl(H2L) (3), and Pb1.5Cl2(H2L) (4). All these compounds exhibited 2D layer substructures with various features based on metal centers and -PO3 groups of the ligands. Differently, the layers cross-linked each other in compounds 1 and 4 via hydrogen bonds generating 3D supramolecular frameworks. While in compounds 2 and 3, they were connected by carboxylate group of the ligands to form 3D pillared-layer frameworks. Such differences were related to the coordination mode of the metal centers, and the pH of the reaction system also played a important role on the coordination ability of the ligands. The magnetic properties reveal the presence of ferromagnetic interactions in compound 1 through a Ni-O-P-O-Ni five-member chain. Luminescent measurements indicate that compounds 2-4 each displays strong blue fluorescent emissions.
