"All forms of ferric chloride are paramagnetic, owing to the presence of five unpaired electrons residing in 3d orbitals. This electronic configuration places electrons in molecular orbitals that are antibonding with respect to ligands. Thus, iron(III) chlorides are labile, undergoing rapid ligand exchange in solution. In contrast to their kinetic lability, iron(III) chlorides are thermodynamically robust… " - Fecl3 standard heat of formation
