Abstract

Structures à la carte: the combination of lone pairs and halide ions yields a praseodymium antimony oxohalide nanocluster [Pr(4)Sb(12)O(18)Cl(17)](5-) with nearly perfect T(d) symmetry. Inorganic-organic hybrid compounds with 1D chain structure and 2D wave layer structure were assembled using dicarboxylic ligands with angular or linear geometry to interconnect the nanoclusters as secondary building units.
