二氯化四(二甲基亞碸)合釕(II)是一種配位化合物，化學式為RuCl₂(DMSO)₄，其中，DMSO為二甲基亞碸的英文縮寫。它存在順式和反式兩種構型，這兩種構型都是已知的，但順式構型（如右圖）更為常見。順式異構體為黃色固體，在空氣中穩定，可溶於一部分有機溶劑。它是潛在的抗癌藥物。

結構與製備

順式異構體為DMSO配體連接異構。^[1]三個DMSO配體為S-鍵合，另一個為O-鍵合，對於兩個Cl來說是順式構型。反式異構體也是黃色的，但四個DMSO配體都是S-鍵合的。順式可以通過熱反應得到，而反式由順式通過紫外線照射得到。^[2]


cis,fac-異構體	trans,mer-異構體

這些配合物最初由三氯化釕的DMSO溶液在氫氣氣氛中加熱得到。^[3]另一種不使用氫氣的方法也得到了文獻報道。^[2]^[4]

反應

順式RuCl₂(DMSO)₄和乙酰丙酮、碳酸氫鈉在乙醇中回流反應，經提純後可以得到黃色的順式二(乙酰丙酮)二(二甲基亞碸)合釕(II)（cis-Ru(DMSO)₂(acac)₂）。^[5]它和苯胺在常溫下甲醇-氯仿（2:1）中反應，配位原子為氧的DMSO配體被取代，得到淺黃色的cis,fac-[RuCl₂(DMSO)₃(NH₂C₆H₅)]；若在甲醇中回流反應，則配位原子為氧和硫的兩個DMSO配體被取代，得到深黃色的trans,cis,cis-[RuCl₂(DMSO)₂(NH₂C₆H₅)₂]。^[6]

潛在應用

RuCl₂(DMSO)₄最初於20世紀80年代早期被認定為抗癌藥。^[7]後期進一步的研究^[8]^[9]使得其它含DMSO的釕化合物得到了開發，其中一些進行了早期的臨床試驗。^[10]
