每周分子： 十二羰基三钌
Molecule of the Week:
Trirutheniumdodecacarbonyl
十二羰基三钌 [Ru 3 (CO) 12 ] 是一种配位化合物，由三个钌原子形成三角形结构，每个钌原子与四个一氧化碳分子键合。其为深橙色晶体，可溶于非极性溶剂，但不溶于水 。
Ru 3 (CO) 12 和的十二羰基锇 1 [Os 3 (CO) 12 ] 具有相似结构，它们最初被报道的分子式分别为Ru 2 (CO) 9 和Os 2 (CO) 9 。之后威斯康星大学 (美国麦迪逊分校) 的Eugene E. Corey和Lawrence F. Dahl于1961年对其进行了广泛的分析，揭示了以前无法预见的三角形的分子结构。他们使用晶体学和光谱学数据确定了其分子结构 。
Ru 3 (CO) 12 是通过三氯化钌 2 (RuCl 3 ) 与CO的碱催化液相反应合成的。它也可以在高CO压力下由溶解在环己烷中的硬脂酸钌 3 或由RuCl 3 和金属锌在乙醇中制成。
Ru 3 (CO) 12 的主要用途是合成其他钌络合物，其中许多是CO与其他配体 (如烯烃) 结合而成。Tokyo Electron公司 (东京) 最近的两项专利披露了其用于制造沉积在形成半导体的硅底物上的钌膜的用途 。
今年，Ru 3 (CO) 12 也被用于教学。它与其他六种具有不同类型对称性的无机分子一起，被伊利诺伊大学芝加哥分校的Donald J. Wink及其合作者们用来指导学生识别对称元素。此项 4 教学活动包括指导学生创建的2-D绘图和3-D分子模型 。
CO和大多数钌化合物具有剧毒，而Ru 3 (CO) 12 则表现出非常小的危害 。

Triruthenium dodecacarbonyl [Ru 3 (CO) 12 ] is a coordination compound that consists of a triangle of ruthenium atoms, each of which is bonded to four carbon monoxide molecules. It appears as dark orange crystals that are soluble in nonpolar solvents but not in water .
Ru 3 (CO) 12 and the similar osmium dodecacarbonyl 1 [Os 3 (CO) 12 ] were originally reported to have the formulas Ru 2 (CO) 9 and Os 2 (CO) 9 , respectively. But an extensive analysis in 1961 by Eugene E. Corey and Lawrence F. Dahl at the University of Wisconsin (Madison) revealed the previously unforeseen trigonal structures of the molecules. The authors used crystallographic and spectroscopic evidence to establish the molecular structures .
Ru 3 (CO) 12 is synthesized via the base-catalyzed liquid-phase reaction of ruthenium trichloride 2 (RuCl 3 ) with CO. It also has been made under high CO pressure from ruthenium stearate 3 dissolved in cyclohexane or from RuCl3 and metallic zinc in ethanol.
The primary use for Ru 3 (CO) 12 is the synthesis of other ruthenium complexes, many with CO combined with other ligands such as alkenes. Two recent patents to Tokyo Electron Ltd. (Tokyo) describe its use for making ruthenium films deposited on silicon substrates that form semiconductors.
This year, Ru 3 (CO) 12 has also been used for an educational purpose. It, along with six other inorganic molecules with varying types of symmetry, were examples used by Donald J. Wink and collaborators at the University of Illinois Chicago to instruct students to recognize symmetry elements. The activity 4 included student-created 2-D drawings and 3-D molecular models.
Considering that CO and most ruthenium compounds are highly toxic, Ru 3 (CO) 12 exhibits remarkably few hazards.

About Molecule of the Week
MOTW has been a popular feature on ACS website since 2001. Many molecules are suggested by our website visitors. Every structure is reviewed by a scientist and displayed in 3-D and flat images with a brief description. Each week’s molecule also links to a sample record from the CAS REGISTRY, which is searched using CAS SciFinder n . Each record displays the registry number, index name and synonyms, bibliographic information, and more. Send us a molecule suggestion at motw@acs.org .
