Transient electron density maps are derived from x-ray diffraction patterns of photoexcited [Fe(bpy)3]2+(PF6−)2 powder. Upon photoexcitation, the 5T2 quintet state reveals a charge transfer from the PF6− ions and from the Fe atoms to neighboring bpy units. The charge transfer from the Fe points to a partial and weak charge-transfer character of this state.
