Benzannulated bisstannylenes, exhibiting a CH 2 C(CH 3 ) 2 CH 2 linking unit and CH 2 t Bu ( 1 ) or CH 2 CH 2 CH 2 NMe 2 ( 2 ) N ‐substituents, and their molybdenum tetacarbonyl complexes 3 and 4 have been prepared. The complexes 3 and 4 exhibit remarkably short MoE bond lengths compared to the related biscarbene and bisgermylene complexes. The experimentally determined bonding parameters of the molybdenum bisstannylene complexes are discussed based on DFT calculations.
