  9. Ammonium iron(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_iron(II)_sulfate

    This compound is a member of a group of double sulfates called Schönites or Tutton's salts. Tutton's salts form monoclinic crystals and have formula M 2 N(SO 4) 2 ·6H 2 O (M = various monocations). With regards to the bonding, crystals consist of octahedra [Fe(H 2 O) 6] 2+ centers, which are hydrogen bonded to sulfate and ammonium. [2]
