A CeIII–CuII Supramolecular Architecture Based on a Trinuclear [Ce(H2O)6(CuL)2] Unit: Synthesis, Crystal Structure and Magnetic Properties

A novel 3d–4f heterometallic coordination complex [Ce(H 2 O) 6 (CuL) 2 ]·NO 2 ·7H 2 O ( 1 ) (H 3 L = glycylglycine, N -[1-(2-hydroxy, phenyl)-propylidene]) was synthesized and characterized by IR, elemental analysis, TGA and single crystal X-ray diffraction. An octameric water cluster consisting of a planar tetrameric water ring and four dangling water molecules were observed in 1 . Variable-temperature magnetic data shows antiferromagnetic behavior for 1 .
