Slow Relaxation of the Magnetisation in a Two-Dimensional Metal–Organic Framework with a Layered Square Lattice by Samia Benmansour, Christian Cerezo-Navarrete, Carlos J. Gómez-García

“…These compounds, formulated as (H₃O)[Eu(C₆O₄(CN)Cl)₂(H₂O)]·34H₂O (<b>1</b>) and (H₃O)[Dy(C₆O₄(CN)Cl)₂(H₂O)]·44H₂O (<b>2</b>), are isostructural and show a (4,4)-layered square structure with the crystallisation water molecules located between the layers. The lanthanoid ions are surrounded by four bis-bidentate chlorocyananilato ligands that connect each Ln^III centre with other four, giving rise to square cavities formed by Ln^III centres in the vertices and chlorocyananilato ligands as the sides. …”
