Pseudohalogenogermylenes [(iBu)₂ATI]GeY (Y=NCO 4, NCS 5) show different coordination behavior towards group 6 metal carbonyls in comparison to the corresponding halogenogermylenes [(iBu)₂ATI]GeX (X=F 1, Cl 2, Br 3) (ATI=aminotroponiminate). The reactions of compounds 4–5 and 1–3 with cis‐[M(CO)₄(COD)] (M=Mo, W, COD=cyclooctadiene) gave trans‐germylene metal complexes {[(iBu)₂ATI]GeY}₂M(CO)₄ (Y=NCO, M=Mo 6, W 11; Y=NCS, M=Mo 7) and cis‐germylene metal complexes {[(iBu)₂ATI]GeX}₂M(CO)₄ (M=Mo, X=F 8, Cl 9, Br 10; M=W, X=Cl 12), respectively. Theoretical studies on compounds 7 and 9 reveal that donor–acceptor interactions from Mo to Ge atoms are better stabilized in the observed trans and cis geometries than in the hypothetical cis and trans structures, respectively.
