Abstract

Terbium(III) (I) and cobalt(III) (II) complexes derived from tripodal Schiff bases tris(2-((5-chlorosalicylidene)amino)ethyl)amine (H3La) and tris(2-((4-methoxysalicylidene)amino)ethyl)amine (H3Lb), respectively, have been prepared and characterized by elemental analyses, IR, and single crystal X-ray crystallographic determination (CIF files CCDC nos. 1021371 (I) and 1021372 (II)). The crystal of [Tb(La)3] (I) is monoclinic: space group P21/n, a = 12.689(1), b = 15.301(1), c = 15.099(1) Å, β = 110.484(2)°, V = 2746.2(4)Å3, Z = 4, R 1 = 0.0314, wR 2 = 0.0801. The crystal of [Co(Lb)3)]2 · MeCN (II) is triclinic: space group $$P\bar 1$$ , a = 12.3031(6), b = 13.7209(7), c = 17.884(1) Å, α = 83.785(2)°, β = 88.144(2)°, γ = 87.873(1)°, V = 2998.0(3) Å3, Z = 2, R 1 = 0.0669, wR 2 = 0.1538. The tripodal Schiff base ligands coordinate to the metal atoms through three phenolate O and three imine N atoms. The Tb atom in complex I is in a monocapped octahedral coordination, and the Co atom in complex II is in octahedral coordination. The effects of the complexes on the antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans were studied.
