Crystal Structure of a Lithiumsilylamidebutanide Colorless single crystals of {Li 6 [Me 2 (H)Si—N—Si(H)—(CHMe 2 ) 2 ] 2 [n‐C 4 H 9 ] 4 } ( 1 ) were obtained from a solution of Me 2 (H)SiN(Li)Si(H)(CHMe 2 ) 2 and n‐C 4 H 9 Li in n‐hexane. The X‐ray analysis showed that the core of 1 is a distorted octahedron of lithium atoms with ten long and with two short LiÄLi distances. Four of the eight triangular Li 3 faces are capped by an n‐butyl group. The nitrogen atoms of the amide groups are situated about opposite edges of adjacent unoccupied Li 3 faces. (Si)H····Li interactions exist between the hydridic H atom of each Me 2 (H)Si group and one Li atom.
