Abstract

Reaction of potassium salt of N-aryliminopyrrole ligand [2-(2, 6-iPr 2C6H3N=CH)-C4H3NK] (1) with samarium tris-boro-hydride [Sm(BH4)3(THF) 3] gave a samarium ate complex [η2-{2-(2, 6-iPr 2C6H3N=CH)-C4H3N} 3Sm(η1-BH4){K(THF)6] (2); whereas similar treatment with erbium borohydride [Er(BH4) 3(THF)3] afforded the mono(iminopyrrolyl) complex [η2-{2-(2, 6-iPr2C6H3N=CH)- C4H3N}Er(η3-BH4) 2(THF)2] (3). In the solid-state structures, the samarium complex 2 shows a rarely observed η1 and the erbium complex 3 shows a usual η3 coordination mode of the borohydrido ligand. Copyright
