Pentanuclear tetra-decker luminescent lanthanide Schiff base complexes†
Abstract
Luminescent pentanuclear tetra-decker Ln(III) complexes [Eu5L4(OH)2(NO3)4(H2O)2]·NO3·3H2O 1, [Nd5L4(OH)2(NO3)5MeOH]·3MeOH·2H2O 2 and [Eu5L4(CF3SO3)4(MeO)2(H2O)4]·CF3SO3·H2O 3 are formed from Ln(NO3)3·6H2O (Ln = Eu (1), Nd (2)) and Eu(CF3SO3)3, respectively (H2L = N,N′-bis(5-bromo-3-methoxysalicylidene)phenylene-1,2-diamine).
