'''五氯化钨''' 是一种[[钨]]的[[氯化物]]，化学式W<sub>2</sub>Cl<sub>10</sub>。

== 制备 ==
五氯化钨可以由[[六氯化钨]] 被 [[氢气]]在 350–400 °C 下还原而成。[[四氯乙烯]]在 100 °C 且光照下还原六氯化钨也能产生五氯化钨。<ref name="brauer">[[Georg Brauer]] (Hrsg.) u.&nbsp;a.: ''Handbuch der Präparativen Anorganischen Chemie.'' 3., umgearbeitete Auflage.

== 性质 ==
五氯化钨是一种黑色[[顺磁性]]固体，会[[潮解]]。它在水中立即分解，在干燥的[[二硫化碳]]中则微溶。 二聚体的<ref name="Erwin Riedel, Christoph Janiak">{{Literatur | Autor  = Erwin Riedel, Christoph Janiak | Titel = Anorganische Chemie | Verlag = Walter de Gruyter | ISBN = 3110225670 | Jahr = 2011 | Online = {{Google Buch | BuchID = r9jDGpBD7i0C | Seite = 825 }} | Seiten = 825 }}</ref> 五氯化钨具有与[[五氯化钼]]一样的[[晶体结构]]。 <ref name="brauer" /> 五氯化钨在气相的结构是三角双锥的WCl<sub>5</sub>单体。 <ref>[[F.
