摘要

Reaction of the sterically demanding ligand precursor [(CHBu2t)(C5H2Bu2t)(2)]K-2 with SnCl2 in THF gave the air-stable ansa-stannocene complex rac-[(CHBut)(2)(C5H2Bu2t)(2)]Sn. A single-crystal X-ray structure of the ansa-stannocene revealed a C-2-symmetric and slipped bent structure, with the Sn2+ displaced toward an eta(2) bonding mode between bridged, highly tilted, and staggered 2,4-di-tert-butylcyclopentadienyl rings.
