Stibinidene complexes are rare and highly sensitive low‐valent main group compounds, which have not been studied extensively for their reaction behavior so far. In the reaction with GaCl 3, the stibinidene complex [ClSb{Cr(CO) 5 } 2 (thf)] ( 1 ) shows a dimerization to [ClSb{Cr(CO) 5 } 2 ] 2 ( 2 ) and yields the anionic double‐chlorinated compound [Cl 2 Sb{Cr(CO) 5 } 2 ] − ( 3 ) in the reaction with different ionic nucleophiles. When using neutral nucleophiles (such as amines, isocyanides and phosphines) as reaction partners, tetrahedral complexes of the type [ClSb{Cr(CO) 5 } 2 Nu] ( 4 : Nu=NH 2 Mes; 5 : Nu=CN(dmp); 6 : Nu=PPh 3 ; 7 : Nu=PPh 2 H) are formed which can be used in subsequent reactions. All of these products are among the first of their type to be synthesized and isolated.
