Abstract
Manganese(III) complexes derived from the bis-Schiff bases N,N′-bis(5-fluorosalicylidene)-1,2-diaminoethane (H2La) and 3,4-bis(2-hydroxybenzylideneamino)pyridine (H2Lb), respectively, have been prepared and characterized by elemental analyses, IR, and single crystal X-ray crystallographic determination (CIF files CCDC nos. 997243 (I), 995896 (II)). The crystal of [MnLa(μ1,3-N3)] n (I) is orthorhombic: space group Pca21, a = 10.723(1), b = 13.430(1), c = 11.112(1) Å, V = 1600.2(2) Å3, Z = 4, R 1 = 0.0264, wR 2 = 0.0649. The crystal of [MnLb(N3)(CH3OH)] (II) is monoclinic: space group C2/c, a = 22.792(1), b = 14.4442(7), c = 12.8637(6) Å, β = 119.262(1)°, V = 3694.5(3) Å3, Z = 8, R 1 = 0.0367, wR 2 = 0.0776. The bis-Schiff base ligands coordinate to the metal atoms through phenolate O and imine N atoms. Each metal atom in the complexes is in octahedral coordination. The effects of the complexes on the antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans were studied.
