The present paper reports the crystal structure and luminescent properties of bis(benzo‐15‐crown‐5)europium(II) diperchlorate. The structure is composed of complex bis(benzo‐15‐crown‐5)europium(II) cations and perchlorate anions. The complex cation is centrosymmetric, and the metal ion is surrounded by 10 oxygen atoms of two ligand molecules. The compound shows very bright luminescence at 23450 cm −1 . The emission parameters (wavelength and the average lifetime of the excited state) are compared to those previously reported for the analogous complex in methanol solutions.
