✦ Synopsis

Three new heptanuclear trigonal prismatic polyhedra, [LnCu 6 (m 3 -OH) 3 (Gly) 6 im 6 ](ClO 4 ) 6 (Ln ¼ La (1), Sm (2), Er (3)) were synthesized through the self-assembly of Ln 3þ , Cu 2þ , glycine and imidazole in aqueous solution and characterized by X-ray structure analysis. The complexes crystallize in the rhombohedral R3 space group (a ¼ b
