摘要：

Bond lengths and angles of the C--NC unit of 1 prove that the negative charge is stabilized by the inductive effect of the N atom of the isocyanide group, in accord with earlier experimental results and theoretical predictions. However, the planar environment of the anionic C atom as well as the fact that 1 is monomeric in the crystal are contrary to ab initio calculations on the parent compound LiCH2NC. This is the result of the strong electronic influence of the two phenyl groups.
