Route 1: Solvothermal

238 · Synthesis of EuL

Metal precursorsEu(NO3)3.6H2O (0.112 mmol, 50 mg)

Linker precursorsBiphenyl-3,4',5-tricarboxylate / H3BPT (0.07 mmol, 20 mg)

SolventsDMF (1.0 mL) and H2O (1.0 mL)

Additivesnone reported

Atmospheresealed 10 mL glass vial; atmosphere otherwise not specified

Temperature80

Time24

Oxidant / reductantnone reported

Work-upcooled to room temperature; colourless crystals collected and air-dried

Activationnone for as-synthesised crystals

Scalability context87% yield based on H3BPT; authors state a moderate ligand:metal ratio gave higher purity and yield than a prior excess-reagent method.
