对一类新型阴离子络盐Ｍ＾＋〔（μ－ＣＯ）（μ－ＲＳ）Ｆｅ２（ＣＯ）６〕＾－（Ｍ＾＋＝Ｅｔ３ＮＨ＾＋，Ｌｉ＾＋，Ｎａ＾＋，ＭｇＸ＾＋）的合成、结构和反应进行了综述。该类络直已成为一种有效试剂，它在新颖金属有机和原子簇化合物的合成中具有广泛的应用价值。

The synthesis, structure and reactions of the new type of butterfly-shaped anioniccomplex salts M+[μ-CO) (μ-RS)Fe2(CO)6]-(M+=Et3NH+,Li+,Na+,MgX+) have beenreviewed. The complex salts were usually prepared by the action of alkanethiolates orarenethiolates RS-M+ on Fe3(CO)_(12) in THF and used in situ for subsequent reactions. Thesingle-crystal X-ray diffraction analysis confirmed that this kind of compsplex salts had a butterfly-shaped framework consisting of Fe_2SC atoms.The complex salts are highly reactivetowards diverse electrophilic substrates.Such substrates, generally, include unsaturatedalkyl halides,acid chlorides,alkynes,halides of phosphorus and arsenic,carbon disulfide,sulfur(1) chloride, elemental sulfur and selenium and alkylmercuric chlorides etc..Apparently,such a kind of anionic complex salts has become a very effective reagent and has beenused extensively in the syntheses of novel organometallic and cluster complexes.
