Beschreibungen/Notizen

• Benzannulated bisstannylenes, exhibiting a CH2C(CH3)2CH2 linking unit and CH2tBu (1) or CH2CH2CH2NMe2 (2) N‐substituents, and their molybdenum tetacarbonyl complexes 3 and 4 have been prepared. The complexes 3 and 4 exhibit remarkably short MoE 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. Falling short! Molybdenum complexes of benzannulated N‐heterocyclic bisstannylenes exhibit remarkable short MoE bonds (an example is shown here) compared to their carbene and germylene analogues. The experimentally determined bonding parameters in molybdenum bisstannylene complexes are discussed based on spectroscopic measurements and DFT calculations.
