The reaction of iron(Ⅲ)anions,FeCl 3 and Fe 2(SO 4)3 with tris(hydroxymethyl)aminomethane(Tris)in a 1∶2 molar ratio affords the new coordination compounds NH 4[Fe 2(Tris)2(H 2O)4(SO 4)](Ⅰ)and NH 4[Fe(Tris)2(H 2O)2]...The reaction of iron(Ⅲ)anions,FeCl 3 and Fe 2(SO 4)3 with tris(hydroxymethyl)aminomethane(Tris)in a 1∶2 molar ratio affords the new coordination compounds NH 4[Fe 2(Tris)2(H 2O)4(SO 4)](Ⅰ)and NH 4[Fe(Tris)2(H 2O)2](Ⅱ).These compounds were characterized by elemental analysis,and their molecular structures were determined by spectroscopic methods(infrared and electronic spectra),magnetic susceptibility,and molar conductivity measurements,and further corroborated by thermo gravimetric analysis and its differential(TGA/DrTGA).According to the experimental data,the complexes can be characterized in the solid state as mono-and binuclear,with a distorted octahedral stereochemistry.The distorted octahedral stereochemistry adopted by the complexes was confirmed by the magnetic susceptibility measurement of NH 4[Fe 2(Tris)2(H 2O)4(SO 4)],which consists of a six-coordinate iron atoms in a distorted octahedral environment constructed from four O atoms(two Tris molecules),two O atoms from the loosely associated SO 4 coordinated ligand,and O,N of second Tris molecule with occupying by four oxygen atoms of coordinated water molecules.Regarding,NH 4[Fe(Tris)2(H 2O)2]complex the mono iron atom is surrounded by six oxygen atoms as four by two Tris molecules and two coordinated water molecules in axial form.Antibacterial and anticancer activities of the complexes were studied and the complexes were screened against bacteria,colorectal adenocarcinoma(Caco-2)and breast cancer(Mcf-7)cell lines.展开更多
