The title complex [Mg(H2O)6]·(L)·(H2O) [L=2-formyl-benzenesulfonate-hydrazine] was synthesized by the reaction of magnesium chloride hexahydrate with 2-formyl-benzenesulfonic acid sodium-hydrazine in the CH3CH2OH/H2O.It was characterized by elemental analysis,IR and X-ray single crystal structure analysis.The crystal of the title complex [Mg(H2O)6]·(C14H12N2O7S2)·(H2O) belongs to triclinic,space group P1 with a=0.781 09(12) nm,b=0.781 27(13) nm,c=0.995 68(19) nm,α=102.054(2)°,β=92.331 0(10)°,γ=105.500(2)°,V=0.569 59(17) nm3,Z=1,Dc=1.559 Mg·m-3,μ=0.334 mm-1,F(000)=280,and final R1=0.033 9,wR2=0.091 6.The complex comprises a six-coordinated magnesium(Ⅱ) center,with a O6 distorted octahedron coordination environment.The molecules are connected by hydrogen bonds to form two dimensional network structures.
A new complex hexaaquamagnesium(Ⅱ) bis [2-(thiosemicarbazonomethyl)-benzoato],has been prepared and characterized by elemental analysis,IR spectra,molar conductivity and single-crystal X-ray diffraction. The results of crystal structure show that each Mg(Ⅱ) ion is coordinated with six oxygen atoms from water molecules and the complex formed two dimensional layered structure through intramolecule and intermolecule hydrogen bonds. The antibacterial assay of the magnesium(Ⅱ) complex and the ligand were tested using a modified version of the 2-fold serial dilution method,the results show that the complex show considerable antibacterial activity against escherichia coli,bacillus subtilis and staphylococcus white,and the ligand did not show antibacterial activity.
