Abstract
In the search of new multifunctional molecular materials, the present paper introduces the work performed with the Salen-type Schiff base: bis-N,N'-p-bromo-salicylideneamine-1,2-diaminobenzene (H-2-bsph), to attain novel coordination complexes containing lanthanides centers (Ln(III)). So far, our studies have shown that the combination in acetone of the well-known H(2)bsph ligand, a base and Nd-III(NO3)(3-)center dot 6H(2)O, results in a yellow solid which crystalline forms has been suitable for X-ray diffraction studies. As a result, a novel Nd-III system has been achieved, with formula [Nd-2(bsph)(3)(H2O)]center dot 2CH(3)Cl (1). The architecture of 1 encloses two metal centers inserted among three Schiff bases (2Nd(III):3(bsph(2-))) resembling a sandwich-shape, is a rare example of triple-decker coordination species with only few similar systems described in the literature. The magnetic properties of 1 have been examined as well as the luminescence activity; the latest was compared with H(2)bsph for better interpretation. (C) 2013 Elsevier Ltd. All rights reserved.
