The structural characterization of the first beryllium amide possessing nitrogen-bridged Be(II) and Sn(IV) metal centers: Synthesis and X-ray study of [(Me3Sn)2NBe(Cl) · (THF)]2

The reaction of the homoleptic lithium stannylamide, [(Me3Sn)2NLi · (THF)]2, with BeCl2 yields the beryllium amide, [(Me3Sn)2NBe(Cl) · (THF)]2. X-ray structural analysis reveals that the complex is comprised of a beryllium dimer possessing bridging amide moieties and terminal chloride ligands. This product represents the first compound containing nitrogen-bridged Be(II) and Sn(IV) metal centers.
