| Abstract: A new complex bis(N-benzenesulphonyl-L-phenylalanine-O)-bis(water-O)-(1,10-phenanthroline-N,N′)-magnesium(Ⅱ) ([Mg(BPPA)2(phen)(H2O)2]·(phen)·2(H2O)), has been prepared and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The results showed that the compound was triclinic, with P1, a=07.087 0(10) nm, b=1.324 80(15) nm, c=1.621 8(2) nm, α=111.854(2)°, β=101.300(10)°，γ=95.645(10)°, V=1.361 1(3) nm3, Z=1, Mr=1 065.45, Dc=1.300 g·cm-3, T=298(2) K, F(000)=558, μ(Mo Kα)=0.176 cm-1, Flack= 0.07(11), N=0.048 4, wR=0.110 8, The complex formed one dimensional chain structure through intramolecule and intermolecule hydrogen bonds and π-π stacking. The antibacterial assay of the magnesium(Ⅱ) complex and the ligand of N-benzenesulphony-L-phenylalanine was tested using a modified version of the 2-fold serial dilution method. The complex shows considerable antibacterial activity against escherichia coli, bacillus subtilis and staphylococcus white, and the ligand did not show antibacterial activity. CCDC: 744536. |
