title: (1R,2R)-(-)-Bis[mu4-1-[[1,1-dimethyl-2-(trimethylsilyl)amidino]amino]-2-([1,1-dimethyl-2-[1,1-dimethyl-2-(trimethylsilyl)amidino]amidino]amino)cyclohexane]tetralithium(I).
abstract: The title compound, [Li(4)(C(21)H(46)N(8)Si(2))(2)], has been prepared and its structure determined. The whole molecule can be regarded as a molecular cage made up of the central eight-membered ring and six contiguous rings of three types. As the first example of a bridged amidinate-dicyanamide framework, this noteworthy structure and its electronic features are presented.
