Five monocarba‐bridged bis(cyclopentadienyl)aluminum halide NHC and thione complexes and one monocarba‐bridged bis(cyclopentadienyl)phosphanylalane NHC complex are reported. The former were synthesized by transmetalation of a C[1]magnesocenophane with the corresponding aluminum(III) chloride and aluminum(III) bromide donor adducts. The phosphanylalane complex was obtained by a subsequent functionalization of the corresponding bromoalane with lithium diphenylphosphide. All complexes were characterized in solution by multinuclear NMR spectroscopy and in the solid state by single crystal X‐ray diffraction. Bonding energies of the NHC and thione ligands to the aluminum centres were estimated by DFT calculations.

供体稳定的单卡巴桥联双（环戊二烯基）丙烷

报道了五种单卡巴桥联的双（环戊二烯基）铝卤化物 NHC 和硫酮配合物和一种单卡巴桥联的双（环戊二烯基）膦基丙烷 NHC 络合物。前者是通过 C[1] magnesocenophane 与相应的氯化铝 (III) 和溴化铝 (III) 供体加合物的金属转移合成的。通过随后用二苯基磷化锂使相应的溴丙烷官能化获得磷酰丙烷络合物。所有配合物在溶液中通过多核 NMR 光谱进行表征，在固态通过单晶 X 射线衍射进行表征。NHC 和硫酮配体与铝中心的键合能通过 DFT 计算估算。
