Toward constructing nanoscale hydroxo-lanthanide clusters: syntheses and characterizations of novel tetradecanuclear hydroxo-lanthanide clusters

Two novel tetradecanuclear hydroxo-lanthanide complexes, formulated as Ln(14)(mu(4)-OH)(2)(mu(3)-OH)(16)(mu-eta(2)-acac)(8)(eta(2)-acac)(16), Ln = Tb, 1; Eu, 2; acac = acetylacetonato, were synthesized and characterized by single-crystal X-ray diffraction, elemental analysis and phosphorescence spectroscopy.
