Abstract

Reaction of the sterically demanding ligand precursor [(CHBu&lt;SUP&gt;t&lt;/SUP&gt;)&lt;INF&gt;2&lt;/INF&gt;(C&lt;INF&gt;5&lt;/INF&gt;H&lt;INF&gt;2&lt;/INF&gt;Bu&lt;SUP&gt;t&lt;/SUP&gt;&lt;INF&gt;2&lt;/INF&gt;)&lt;INF&gt;2&lt;/INF&gt;]K&lt;INF&gt;2&lt;/INF&gt; with SnCl&lt;INF&gt;2&lt;/INF&gt; in THF gave the air-stable ansa-stannocene complex rac[(CHBu&lt;SUP&gt;t&lt;/SUP&gt;)&lt;INF&gt;2&lt;/INF&gt;(C&lt;INF&gt;5&lt;/INF&gt;H&lt;INF&gt;2&lt;/INF&gt;Bu&lt;SUP&gt;t&lt;/SUP&gt;&lt;INF&gt;2&lt;/INF&gt;)&lt;INF&gt;2&lt;/INF&gt;]Sn. A single-crystal X-ray structure of the ansa-stannocene revealed a C&lt;INF&gt;2&lt;/INF&gt;-symmetric and slipped bent structure, with the Sn&lt;SUP&gt;2+&lt;/SUP&gt; displaced toward an η&lt;SUP&gt;2&lt;/SUP&gt; bonding mode between bridged, highly tilted, and staggered 2,4-di-tert-butylcyclopentadienyl rings.
