Abstract
Two novel decanuclear Ln(III) compounds (Ln=Pr for 1, Nd for 2) have been solvothermally obtained by using p-tert-butylcalix[8]arene (H8TBC8A) and phenylphosphonate (PhPO3H2) as ligands. Single crystal X-ray diffraction studies reveal that both compounds are stacked by dumbbell-like Ln10 clusters, which are capped by two TBC8A8− supports and linked by four complementary PhPO32− ligands as well as other bridging anions. In addition, the self-assembly behavior of both compounds is interesting: the cationic Ln10 cluster layers are separated by the layers of H6TBC8A2− ligands. Moreover, the luminescent and magnetic properties of both compounds were examined.
Utilizing phosphonate as co-ligand, two novel decanuclear Ln10 clusters (Ln=Pr, Nd) based on p-tert-butylcalix[8]arene (H8TBC8A) with interesting self-assembly properties are reported: the cationic Ln10 cluster layers are separated by the anionic layers of co-crystallized H6TBC8A2− ligands.
