Synthesis, Crystal Structure and Antibacterial Activity of Mg(II) Complex [Mg(H₂O)₆]·(4-amino-3-methylbenzenesulfonate)₂

摘要

A Mg(II) complex, [Mg(H₂O)₆]·L₂ (H₂L = 4-amino-3-methylbenzenesulfonate), has been synthesized and characterized by elemental analysis, Infrared (IR) and single-crystal X-ray diffraction. The results indicated that the Mg(II) complex was monoclinic with P2₁, a = 6.3184(16) Å, b = 7.0522(18) Å, c = 24.434(6) Å, β = 93.946(3)°, V = 1086.2(5) Å3, Z = 2, Mr = 504.81, Dc = 1.544 g/cm3, T = 296(2) K, F(000) = 532, μ(MoKa) = 0.338 mm−1, R = 0.0339 and wR =0.1194. The Mg(II) ion lies in a distorted octahedral geometry. The hydrogen bonds and π-π stacking interaction play an important role in the forming of one dimensional chain structure. The antibacterial activity against Escherichia coli, Bacillus subtilis and Staphylococcus white of the Mg(II) complex has also been investigated.
