Abstract

The new heteronuclear iminodiacetic acid (H₂L) complexes [LnCu₆(μ₃-OH)₃(HL)₂(L)₄](ClO₄)₂·25H₂O with Ln = La (1) and Tb (2) have been prepared in aqueous solution and characterized by single-crystal X-ray diffraction to be isomorphous (crystallographic data for 1 and 2: hexagonal, P6₃/m; a = b = 12.6425(14) Å, c = 24.541(5) Å, Z = 2 (1); a = b = 12.5802(9) Å, c = 24.285(4) Å, Z = 2 (2)). Ln³⁺ was found to be located in the center of the trigonal prismatic cage formed by six Cu²⁺ ions, with a tricapped trigonal prismatic coordination environment of nine O atoms. The magnetic properties of complexes 1 and 2 have been studied. The results indicate the presence of ferromagnetic couplings between Tb³⁺ and Cu²⁺ in compound 2.
