Two lanthanide(III)/phenanthroline/p-sulfonatocalix[4]arene supramolecular compounds with 1D ‘molecular capsule’ chains

Two supramolecular complexes, [Ln3(H2O)17(C12H8N2)3][(C28H20S4O16)(C28H19S4O16)](C12H8N2)[H2O]32 (Ln = Nd (1) and Ce (2)), have been hydrothermally synthesized and structurally determined by single crystal X-ray diffraction, TG analysis and IR spectroscopy. The extended structures are featured with the 1D ‘molecular capsule’ chains constructed by the lanthanide-hinged capsules. Some 2D water clusters are also observed in the structures.
