资源简介：
A novel binuclear ytterbium(II) complex supported by a naphthalene-bridged bis(guanidinate) ligand, [Yb(μ-L)(THF)]2 (1; L = 1,8-C10H6{NC(NiPr)(NHiPr)}2), was synthesized by the reduction reaction of [Yb(L)Cl(THF)2] with Na/K alloy in THF and structurally characterized. The reactions of 1 with CH3CN and p-ClC6H4CH2CN resulted in the formation of the corresponding binuclear (crotononitrileamido)ytterbium(III) complexes [Yb(L)(μ(N,N′)-N(H)C(Me)C(H)CN)(THF)]2 (2) and [Yb(L)(μ(N,N′)-N(H)C(CH2C6H4-p-Cl)C(C6H4-p-Cl)CN)(THF)]2 (3) via metalation of the nitrile, followed by insertion of a second nitrile molecule. Treatment of 1 with the bulkier Ph2CHCN afforded the mononuclear (keteniminato)ytterbium(III) complex [Yb(L)(NCCPh2)(THF)2] (4) by deprotonation of Ph2CHCN. The molecular structures of 2–4 have been determined.
