Abstract

The treatment of ortho ring-functionalised 1-phenylbutane-1,3-dione ligands bearing nitro (Hnpd, Hnmc), methoxy (Hmmc) or fluoro (Hfpp) groups with hydrated lanthanoid salts has provided [Er4(μ3-OH)4(H2O)2(npd)8] (3), [Ln4(μ3-OH)4(nmc)8] (Ln = Gd (4), Tb (5), Dy (6) and Er (7)), [Er4(μ3-OH)4(mmc)8] (8) and [Er4(μ3-OH)4(H2O)2(fpp)8] (9), respectively. The products were all obtained as cubane clusters in the solid state, as distinct from previous diketonato clusters, with control over motif formation attributed to the steric influence of the ortho-positioned functional groups at the cluster periphery. This work highlights a means of targeting a specific lanthanoid cluster motif by the rational modification of ligands at key locations.
