Single-crystal X-ray diffraction shows that in both cluster compounds, the block blocks of [Dy<sub>26</sub>(μ<sub>3</sub>-OH)<sub>20</sub>(μ<sub>3</sub>-O)<sub>6</sub>(NO<sub>3</sub>)<sub>9</sub>I]<sup>36+</sup>, {Dy<sub>26</sub>}, are the largest cage-shaped lanthanide cluster cores known. Compound <b>1</b> is the first tetramer based on the linkage of two different types of high-nuclearity lanthanide clusters and IN ligands, while compound <b>2</b> represents the first tetramer constructed by {Dy<sub>26</sub>} clusters and IN linkers. 2007-04-16 00:00:00 lanthanide cluster core backbone surface modifiers cluster cores Compound 1 novel lanthanide cluster compounds compound 2 104I Surface Modification 30I Dy cluster compounds Tetramers Constructed HIN Isonicotinate LinkersBy incorporation hydrothermal conditions block blocks
