摘要：

A series of trifunctional amines of the type H3CC(CH2NHR)3 [R = CH32, C2H5 3, CH(CH3),4, SiH(CH3),5 or Si(CH3)3 6] has been prepared and lithiated with n-butyllithium in hydrocarbon solvents, The tripodal lithium amides were found to be dimeric both in solution and in the solid state. Single-crystal X-ray structure analyses of {H3CC[CH2N(Li)CH(CH3)2]3}2 9 and {H3CC[CH2N(Li)Si(CH3)2]3}2 11 have established the central Li6N6 core in the molecular species. The geometrical requirements of the Li-N array cause a considerable distortion of the hydrocarbon skeleton which links the nitrogen centres.
