摘要

> Two new series of anionic lanthanide(III) tetrakis(dibenzoylmethanato) complexes of the type [C 4 H 8 NEtH][ Ln (dbm) 4 ] [ Ln = Pr ( 2a ), Nd ( 2b ), Eu ( 2c ), Tb ( 2d ), Lu ( 2e ); dbm = dibenzoylmethanate anion; [C 4 H 8 NEtH] + = N ‐ethylpyrrolidinium cation] and [C 5 H 10 NEtH][ Ln (dbm) 4 ] [ Ln = Pr ( 3a ), Nd ( 3b ), Eu ( 3c ), Tb ( 3d ), Lu ( 3e ); [C 5 H 10 NEtH] + = N ‐ethylpiperidinium cation]. The results showed that anions of the type [ Ln (dbm) 4 ] – are accessible for Ln 3+ ions covering a wide range of ionic radii. While neither 2c nor 3c showed the expected triboluminescence (TL) properties, the new TL‐active europium(III) complex salt [ i Pr 2 NH 2 ][Eu(dbm) 4 ] ( 4 ) could be isolated in a similar manner. Moreover, the unexpected formation and structural characterization of the nonanuclear europium cluster Eu 9
