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

Abstract

Two supramolecular complexes, [Ln 3(H 2O) 17(C 12H 8N 2) 3][(C 28H 20S 4O 16)(C 28H 19S 4O 16)](C 12H 8N 2)[H 2O] 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.
