摘要：

The polyhedral [(C4H9)(4)N][Ni(eta(5)-C5H5)B6H6] has been synthesized from the reaction of closo-hexaborate with two equivalents of nickelocene and one equivalent of Na/Hg amalgam in acetonitrile at room temperature. Crystallization from benzene-acetone gives orange crystals of the title compound in yields of 80-85%. An improved synthesis and isolation of [(C4H9)(4)N]2B6H6 from the reaction of sodium borohydride with boron trifluoride etherate in diglyme in yields of 20-25% is also described.
