title: A first oxalamidino complex of samarium via reduction-coupling of carbodiimine: synthesis and molecular structure of [eta4-C2(NR)4][(MeC5H4)2Sm(HMPA)]2.2THF (R = Pr i, Cy).
abstract: Treatment of the THF solution of (MeC5H4)2Sm(THF) with an equivalent of carbodiimine [RN=C=NR](R = Pr(i) or Cy; Cy = cyclohexyl) in the presence of an equivalent of hexamethylphosphoric triamide (HMPA) at room temperature gives, via a reduction-coupling reaction of carbodiimine, the corresponding bimetallic oxalamidino complex of samarium [eta4-C2(NR)4][(MeC5H4)2Sm(HMPA)]2.2THF.
