Abstract
The Schiff base, N,N′-bis(5-chlorosalicylidene)propane-1,3-diamine (H2L) derived from 5-chlorosalicylaldehyde and propane-1,3-diamine, and its cadmium(II) complex, bis(μ2-acetato)bis(μ2-N,N′-bis(5-chlorosalicylidene)-1,3-propanediamine)tricadmium(II) Cd[Cd(CH3COO)L]2 (I), have been prepared and characterized by elemental analyses, IR, and single-crystal X-ray diffraction analysis. The crystal of H2L is monoclinic: space group P21/n, a = 11.252(4), b = 8.972(3), c = 16.981(6) A, β = 96.005(4)°, V = 1705.0(10) A3, Z = 4. The crystal of complex I is monoclinic: space group P21/c, a = 11.056(1), b = 22.284(2), c = 8.398(1) A, β = 91.779(1)°, V = 2068.0(3) A3, Z = 2. Complex I is a centrosymmetric trinuclear cadmium(II) complex. The deprotonated Schiff base ligand coordinates to the Cd atoms through the phenolate O and imine N atoms. The effect of the Schiff base ligand and the complex on the antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans was studied.
