Ni(COD)₂ reacts with Bu^t₃SnH and CNBu^t at room temperature to afford the trigonal bipyramidal complex Ni(SnBu^t₃)₂(CNBu^t)₃, 3. Exposing a solution of 3 to CO gas results in ligand exchange generating the pale yellow complex, Ni(SnBu^t₃)₂(CNBu^t)₂(CO), 4. In the presence of light, a Ni-Sn bond in 4 is cleaved converting two equivalents of compound 4 into the deep purple nickel-tin dimer, [Ni(SnBu^t₃)(CNBu^t)₂(CO)]₂, 5. The reaction is believed to proceed through radical mechanisms.

镍锡二聚体[Ni（SnBu ^t ₃）（CNBu ^t）₂（CO）] _2的光化学合成和自由基生成。

的Ni（COD）_2层发生反应以卜^吨₃ SNH和CNBu^吨在室温下，得到三角双锥复杂的Ni（SnBu^吨₃）₂（CNBu^吨）₃，3。将3的溶液暴露于CO气体会导致配体交换，从而生成浅黄色络合物Ni（SnBu ^t ₃）₂（CNBu ^t）₂（CO）4。在光的存在下，在Ni-Sn键4被切割转换化合物的两个当量4进深紫色镍-锡二聚体，[镍（SnBu^吨₃）（CNBu^吨）₂（CO）] ₂，5。据信该反应通过自由基机理进行。
