Three lanthanide complexes with mixed salicylate and 1,10-phenanthroline: syntheses, crystal structures, and luminescent/magnetic properties.

Three new lanthanide complexes incorporating salicylate (HSAorSA) and 1,10-phenanthroline (phen), Ln3(HSA)5(SA)2(phen)3[Ln = Ho (1) and Er (2)], and Sm2(HSA)2(SA)2(phen)3(3), have been synthesized. X-ray structural analysis reveals that1and2are isostructural with a trinuclear pattern, and3exhibits a binuclear structure. Comparison of the structural differences between1/2and3suggests that the identity of metal plays an important role in construction of such complexes. The magnetic properties of1are discussed. Moreover,2and3are both photoluminescent materials, and their emission properties are closely related to their corresponding LnIIIcenters. [ABSTRACT FROM AUTHOR]
