摘要: Two structural series, including two isomorphous homodinuclear complexes Ln2(H2O)4(C6NO2H4)6 (Ln = Tb (1) and Er (2)) four isostructural one-dimensional (1-D) chain-like assemblies [Ln(H2O)4(C6NO2H4)2]n·nCl Sm (3), Eu (4), (5), Dy (6)), have been rationally prepared through a facile ultrasonic synthesis characterized by X-ray diffraction photophysical measurements. Both complexes, 1 2, feature structure, based on 8-fold coordination lanthanide atoms bridged nicotinic acid ligands. Complexes 3−6 are 1-D polycationic containing eight-coordinated ions bridging isonicotinic The chains the isolated chloride anions interconnected via hydrogen bonds π-π interactions to form three-dimensional supramolecular network. effect of nicotinic/isonicotinic ligands structures photoluminescence properties, as well relationship ...
