Iron(2+), tris(5-nitro-1,10-phenanthroline-κN1,κN10)-, sulfate (1:1)

Description:

Iron(2+), tris(5-nitro-1,10-phenanthroline-κN1,κN10)-, sulfate (1:1), commonly referred to as iron(II) tris(5-nitro-phenanthroline) sulfate, is a coordination compound featuring iron in the +2 oxidation state coordinated to three 5-nitro-1,10-phenanthroline ligands. This complex exhibits a characteristic deep red color, which is typical of many iron(II) complexes, due to the d-d electronic transitions within the iron ion. The presence of the nitro groups on the phenanthroline ligands enhances the stability and solubility of the complex in various solvents. It is often used in analytical chemistry, particularly in colorimetric assays for iron detection, due to its strong absorbance properties. The sulfate component serves as a counterion, balancing the charge of the complex. Additionally, this compound may exhibit interesting redox properties, making it relevant in studies of electron transfer and coordination chemistry. Safety precautions should be taken when handling this compound, as it may pose health risks if ingested or inhaled.
