Abstract

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/n, 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.

Highlights

During the past few years, inorganic-organic materials have drawn much interest in coordination chemistry because of their easy synthesis and good applications [1,2,3,4,5]
The Mg(II) complex molecules form a 1D chained structure by hydrogen bonds and π-π stacking interaction (Figures 2 and 3), and the hydrogen bonds and π-π stacking interactions increase the stability of the whole crystal structure
The antibacterial activities of the Mg (II) complex against Escherichia coli, Bacillus subtilis and Staphylococcus white were studied as references [11]

Summary

Introduction

During the past few years, inorganic-organic materials have drawn much interest in coordination chemistry because of their easy synthesis and good applications [1,2,3,4,5]. Many coordination compounds show considerable and important applications in luminescence, antibacterial and antitumor agents [6,7,8,9,10]. Relative to other metal cations, Mg(II) ion is an important element for biology [11,12]. Mg complex materials that display biological activities [13,14,15]. Complex was characterized by elemental analysis, single-crystal X-ray diffraction and infrared spectroscopy, and the antibacterial activities of Mg(II) complex have been investigated
