The reaction of K[BH] with [NiCl(dppe)] produces four new 19-vertex macropolyhedral metallaboranes that result from borane cluster fusion: [9'-(dppe)-9'-Ni--BH] () and isomeric [11'-(dppe)-11'-Ni--BH] (), together with the chlorine-substituted derivative of , [5'-Cl-9'-(dppe)-9'-Ni--BH] (), and the 18-vertex cluster compound [7'-(dppe)-7'--NiBH] (). Two 10-vertex single-cluster species, [1-(dppe)-1-NiBHCl] () and [1-(dppe)-1--NiBHCl(OH)] (), were also isolated from the reaction. The production of the metalated -octadecaborane isomer from the fusion of two -nonaborate clusters is the first such case to be observed; in all other reported cases fusion has resulted in products with the octadecaboranyl configuration.
与 [NiCl(dppe)] 的反应产生了四个新的 19 顶点大环多面体金属硼烷，它们是硼烷簇融合的结果：[9'-(dppe)-9'-Ni--BH] () 和异构 [11'-(dppe)-11'-Ni--BH] (), 以及, 的氯取代衍生物 [5'-Cl-9'-(dppe)-9'-Ni--BH] (), 和 18 顶点簇化合物 [7'-(dppe)-7'--NiBH] (). 还从反应中分离出了两个 10 顶点单簇物种，[1-(dppe)-1-NiBHCl] () 和 [1-(dppe)-1--NiBHCl(OH)] (). 两个 -非硼烷簇融合生成金属化 -十八硼烷异构体 是首次观察到的此类情况；在所有其他报道的情况下，融合的产物都具有十八硼烷 构型。
