Abstract:Three heterometallic 3d-4f cluster-based, three-dimensional sulfate frameworks, [Ln(4)Cr(2)(mu(4)-O)(2)(mu(3)-OH)(4)(H2O)(9)(SO4)(5)]center dot 3H(2)O (Ln = Gd/Tb/Dy), were obtained. They are built from the hexanuclear [Ln(4)Cr(2)] cluster and sulfate bridge, showing a 6-connected pcu topology network. The [Gd4Cr2]-based compound displays a large magnetocaloric effect of -Delta S-m = 38.33 J kg(-1) K-1, making it a hopeful magnetic cooler at low temperature, while the Tb- and Dy-containing compounds display interesting single molecule magnet behavior, indicating that they are potential materials to make spintronic devices.
