Reactions of 1,3‐diisopropylcarbodiimide with alkali metal amides, MN(SiMe 3 ) 2 (M=Li or Na) in hexane or THF produced the alkali metal guanidinates {( i ‐PrN) 2 C[N(SiMe 3 ) 2 ]Li} 2 ( 1 ) and {( i ‐PrN) 2 C[N(SiMe 3 ) 2 ]Na(THF)} 2 ( 2 ) in nearly quantitative yields. Both complexes 1 and 2 were well characterized by elemental analysis, IR spectra, 1 H and 13 C NMR spectra, and X‐ray diffraction. It was found that the guanidinates adopt different coordination modes in these complexes.
