Herein, new complexes containing the [Ph 2 PCH 2 S(N t Bu) 3 ] − anion are presented, supplying three imido nitrogen atoms and a remote phosphorus atom as potential donor sites to main group and transition‐metal cations. The lithiated complex [(tmeda)Li{(N t Bu) 3 SCH 2 PPh 2 }] ( 1 ) is an excellent starting material in transmetalation reactions. Herein, the transition‐metal complexes [M{(N t Bu) 3 SCH 2 PPh 2 } 2 ] (M=Mn ( 2 ), Ni ( 3 ), Zn ( 4 )) were synthesized and structurally characterized. Their isotypical molecules show SN 2 chelation and no employment of the adjacent phosphorus atom in coordination. The third pendent imido group is always twisted toward the vacant face of the tetrahedrally coordinated sulfur atom.
