Abstract

Benzannulated bisstannylenes, exhibiting a CH₂C(CH ₃)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.
