The molecular structures of the intramolecularly coordinated tungstenpentacarbonyl organostannylene complexes 2,6‐(Me 2 NCH 2 ) 2 C 6 H 3 (Cl)SnW(CO) 5 and [2,6‐(Me 2 NCH 2 ) 2 C 6 H 3 (H 2 O)SnW(CO) 5 ] + (CB 11 H 12 ) – are reported. The latter compound is an aqua complex in which the water molecule replaces one of the two N→Sn coordination sites. The coordination of the water molecule is accompanied by proton transfer to the nitrogen atom. DFT calculations reveal this to be the thermodynamically most‐stable structure.
