What is Functionalised β-Diketone Assisted Self-assembly of a Hexanuclear Yttrium Oxo-hydroxo Cluster about?

The reaction of YCl 3 Á6H 2 O with ortho-hydroxydibenzoylmethane (HO-DBMH) in a 1:2 ratio, in methanol and in the presence of excess triethylamine as a base yielded a yellow precipitate which on crystallization from toluene or benzene /hexane afforded pale yellow block-like crystals. Single crystal X-ray diffraction of 1 revealed the formation of an interesting hexanuclear yttrium oxo-hydroxo cluster [Y 6 (O-DBM) 6 (HO-DBM) 4 (l 3 -OH) 2 (MeOH) 4 ]; the core resembles a butterfly framework flanked by a lanthanide atom on each side. Ten phenolic b-diketone ligands are present in the cluster, which bridge the metal centers in both chelating and chelating-bridging fashions.
