Pentanuclear tetra-decker luminescent lanthanide Schiff base complexes

摘要

Luminescent pentanuclear tetra-decker Ln(III) complexes [Eu5L4(OH)(2)(NO3)(4)(H2O)]center dot NO3 center dot 3H(2)O 1, [Nd5L4(OH)(2)-(NO3)(5)MeOH]center dot 3MeOH center dot 2H(2)O2 and [Eu5L4(CF3SO3)(4)(MeO)(2)-(H2O)(4)]center dot CF3SO3 center dot H2O 3 are formed from Ln(NO)(3)center dot 6H(2)O (Ln = Eu (1), Nd (2)) and Eu(CF3SO3)(3), respectively (H2L = N, N'-bis(5-bromo-3-methoxysalicylidene)phenylene-1,2-diamine).
