Iron acetate with oxidation state II and iron acetate complex with oxidation state III are known. (1) Iron(II) acetate: Chemical formula Fe(CH 3 COO) 2 . If iron pieces are left in acetic acid for a long time, a tetrahydrate will precipitate. This is a pale green needle-like crystal that belongs to the monoclinic system and dissolves well in water. It will decompose if left in air. (2) Iron(III) acetate: Its composition is equivalent to the normal salt Fe(CH 3 COO) 3 , but its structure is thought to be a trinuclear complex salt such as [Fe 3 (CH 3 COO) 6 ](CH 3 COO) 3 .

酸化数IIの鉄の酢酸塩と酸化数IIIの鉄に酢酸イオンが配位した錯体が知られている。(1)酢酸鉄(II) 化学式Fe(CH3COO)2。鉄片を酢酸中に長時間放置すると4水和物が析出する。これは淡緑色針状晶で単斜晶系に属し,水によく溶ける。空気中に放置すると分解する。(2)酢酸鉄(III) 組成は正塩Fe(CH3COO)3に相当するが,構造は[Fe3(CH3COO)6](CH3COO)3のような三核錯塩であると考えられている。
