Tris(1,10-phenanthroline)iron(II) sulfate

Description:
Tris(1,10-phenanthroline)iron(II) sulfate, commonly referred to as "iron(II) phenanthroline sulfate," is a coordination compound characterized by its vibrant color and complex formation. It consists of an iron(II) ion coordinated to three 1,10-phenanthroline ligands, along with sulfate ions. This compound typically exhibits a deep red to purple hue, which is attributed to the d-d electronic transitions of the iron(II) ion in an octahedral coordination environment. It is soluble in water and commonly used in analytical chemistry, particularly in colorimetric assays for iron and as a redox indicator. The presence of the phenanthroline ligands enhances the stability of the iron(II) complex and allows for the formation of various derivatives. Additionally, this compound is of interest in studies related to electron transfer processes and has applications in photochemistry and materials science. Safety precautions should be observed when handling this compound, as it may pose health risks if ingested or inhaled.
