Abstract

Two kinds of water clusters, the unique dodecahedral (H2O)14 cage and the truncated cubic (H2O)12 cluster formed from both coordinated and lattice water molecules, are captured in three lanthanide complexes [Ln4(chtc)3(H2O)10]·9H2O (Ln = Tb 1, Yb 2, Dy 3, H4chtc = cyclohexane-1,2,4,5-tetracarboxylic acid). Compound 1 exhibits the characteristic photoluminescence of the Tb3+ ion in the visible region, while 2 exhibits NIR luminescence properties.
