'''四氯化铼'''是一种[[无机化合物]]，化学式 ReCl<sub>4</sub>。尽管它被广泛研究，但它没有太大的实用价值。ReCl<sub>4</sub>的第二种{{le|多态性（材料科学）|Polymorphism (materials science)|多晶型物}}也是已知的。 <ref name=FAC/>

==制备==
ReCl<sub>4</sub> 可以由[[五氯化铼]]和[[三氯化铼]]的[[归中反应]]而成。它也可以由[[三氯化锑]]还原[[五氯化铼]]而成。<ref name="Erwin Riedel, Christoph Janiak">{{Cite book |title=Anorganische Chemie |publisher=Walter de Gruyter |year=2011 |isbn=978-311022567-9 |authors=Erwin Riedel, Christoph Janiak}}</ref>
:<math>\mathrm{2 \ ReCl_5 + SbCl_3 \longrightarrow 2 \ ReCl_4 + SbCl_5}</math>

[[四氯乙烯]]在 120 °C 下也是很好的还原剂：
:<math>\mathrm{2 \ ReCl_5 + C_2Cl_4 \longrightarrow 2 \ ReCl_4 + C_2Cl_6}</math>

==结构==
[[X射线晶体学]]揭示了聚合物结构。 Re–Re 键的距离是 2.728 Å。Re 中心是八面体型的，被六个氯原子环绕。一对八面体共面。Re<sub>2</sub>Cl<sub>9</sub>基团通过[[桥接配体|桥接氯配体]]连接。这种结构在二元卤化物是罕见的。<ref name=FAC/>
