Synthesisof crown ether-capped highly symmetrical fluoridecentered lanthanide clusters Ln 6 F 13 (12-crown-4) 6 I 3 F 2 (Ln = Ho, Er)

Key Points

• The aim is to synthesize and characterize lanthanide clusters using crown ethers.
• Synthesis of lanthanide clusters through one-pot reactions.
• Reactants include LnI3, 12-crown-4, and AgBF4 in a 1:2:1 ratio.
• Conducted at room temperature.
• Successfully synthesized two distinct lanthanide clusters: Ho and Er based.
• Both complexes exhibit unique structural features.
