Unprecedented non-cytotoxic [Co4~(III)Ln~(III)]-core complexes with a tripodal oxime ligand -synthesis, structure, properties and potential applications

摘要

A series of [Ln~(III)(H2O)2Co~(III)4O2H_x(Ox3H)4](ClO4)y (Ln = Gd (1), Sm (2), La (3); x = 0, 1; y = 3, 4) complexes (where OX3H3 = tris(2-hydroxyiminopropyl)amine) with a novel-topology heterometallic core are presented. 1 is paramagnetic and 2 is weakly paramagnetic. The complexes were also characterized by IR spectroscopy, EDX, cyclic voltammetry, ESI-MS and elemental analyses. Potential for biological applications was assessed with MTT and stability tests.
