Di( tert ‐butyl)sulfur diimide and bis(trimethylsilyl)sulfur diimide were reacted with different metalated amines to form versatile novel multidentate ligand systems with side‐arm donation. Their complexation properties in terms of ligand design, denticity and the cation size are discussed. We report herein the synthesis and structure elucidation of [( t BuN) 2 S{LiMe 2 N(C 6 H 4 )S(N t Bu) 2 } 2 ] ( 1 ), [(Li{Me 2 N(C 6 H 4 )S(NSiMe 3 ) 2 }) 2 ] ( 2 ), [(Li(thf){Me 2 N(C 6 H 4 )S(NSiMe 3 ) 2 }) 2 ] ( 3 ), [(Li{2‐PicS(NSiMe 3 ) 2 }) 2 ] ( 4 ), [(Li{Me 2 N(CH 2 ) 2 N(Me)S(NSiMe 3 ) 2 }) 2 ] ( 5 ), [(Na{Me 2 N(CH 2 ) 2 N(Me)S(NSiMe 3 ) 2 }) 2 ] ( 6 ) and [(K{Me 2 N(C 6 H 4 )S(NSiMe 3 ) 2 }) 2 ] ( 7 ).
