摘要：

Reaction of LnCl3 & sdot;6H2O (Ln = Pr, Nd) with functionalized beta-Diketone {ortho-hydroxydibenzoylmethane (HODBM)} in 1:2 ratio in methanol and in presence of triethylamine (excess) as base yielded two tetra nuclear lanthanide hydroxo clusters of composition [Ln4(O-DBM)4(HO-DBM)4(mu 3-OH)2][Et3NH]2.3CH2Cl2, (Ln = Pr (1), Nd (2)). The clusters 1 and 2 has been structurally characterized by single crystal X-ray diffraction. A onedimensional supramolecular chain is observed in the solid state structure (2), where dichloromethane solvent molecules are linked to the phenyl rings of adjacent diketone linkers through C-H & ctdot;pi and Cl & ctdot;pi interactions. Theoretical studies support the stability of structure (2), with calculated geometric parameters aligning with experimental findings.
