乙おつ酸さん钼(II)是ぜ一いち种配はい位い化合かごう物ぶつ，化学かがく式しき为Mo₂(O₂CCH₃)₄。它是黄色おうしょく抗こう磁性じせい的てき固体こたい，对空气稳定じょう，微ほろ溶于有ゆう机つくえ溶剂，分子ぶんし中ちゅう存在そんざいMo-Mo四よん重じゅう键。^[1]

结构

乙おつ酸さん钼(II)具有ぐゆう中国ちゅうごく灯とう笼结构，与あずか乙おつ酸さん亚铑、乙おつ酸さん铜和わ乙おつ酸さん亚铬这类二聚乙酸盐同构，^[2]Mo₂(O₂CCH₃)₄晶あきら体からだ属ぞく三さん斜はす晶あきら系けい，P1空そら间群，^[3]分子ぶんし中ちゅう的てき每まい个Mo中心ちゅうしん有ゆう四よん个d层價あたい電子でんし，两个Mo的てき八はち个d电子形成けいせい一いち个σしぐま鍵かぎ、两个πぱい键和わ一いち个δでるた键，形成けいせいσしぐま²πぱい⁴δでるた²电子排はい布ぬの。四よん个乙おつ酸さん根ね桥联两个金属きんぞく中心ちゅうしん。Mo-O的てき键长为2.119 Å，Mo-Mo的てき键长为2.0934 Å。^[4]

制せい备

乙おつ酸さん钼(II)可か由ゆかり六ろく羰基钼和わ乙おつ酸さん反はん应得到いた，反はん应中羰基配はい體たい被ひ乙おつ酸さん根ね取と代だい，放出ほうしゅつ一いち氧化碳，钼从零れい价氧化か至いたり正せい二に价。^[5]^[6]

2 Mo(CO)₆ + 4 HO₂CCH₃ → Mo₂(O₂CCH₃)₄ + 12 CO + 2 H₂

反はん应会产生三核簇作为副产物。^[7]

六羰基钼和乙酸的反应最初由班尼斯特于1960年ねん使用しよう，当とう时金属きんぞく-金属きんぞく四重键未被发现，作者さくしゃ认为制せい得とく的てきMo(O₂CCH₃)₂具有ぐゆう四よん面体めんてい构型。^[8]^[9]后きさき来らい，梅森うめもり对其表ひょう征せい，改あらため变了这一观点。^[10]

应用

Mo₂(O₂CCH₃)₄可用かよう于制备其它含四重键的钼化合物，^[1]反はん应中，乙おつ酸さん根ね配はい体たい可か以被其它配はい体たい取と代だい，如[Mo₂Cl₈]⁴⁻和わMo₂Cl₄[P(C₄H₉)₃]₄。^[1]^[11]^[12]
