摘要：

Ab initio calculations predict the stablest dilithiated alpha-naphthylamine to be the isomer depicted here. The C8 and N atoms are deprotonated and the two Li atoms occupy bridging positions between them. The reaction of alpha-naphthylamine with nBuLi in ether at -40-degrees-C affords the title complex, whose structure is characterized by a central N10Li14 cluster formed by two face-sharing rhombic dodecahedrons. Amazingly the compound is paramagnetic in solution and in the solid.
