AbstractReaction of DyCl(3) with two equivalents of NaN(SiMe(3))(2) in THF yielded {Dy(mu-Cl)[N(SiMe(3))(2)](2)(THF)}(2) (1)-X-ray crystal structure analysis revealed that I is a centrosymmetric dimer with asymmetrically bridging chloride ligands. The metal coordination arrangement can be best described as distorted trigonal bipyramid. The bond lengths of Ln-Cl and Ln-N showed a decreasing trend with the contraction of the size of Ln(3+). Treatment of N,N-bis(pyrrolyi-alpha-methyl)-N-methylamine (H(2)dpma) with 1 and known compound {Yb(mu-Cl)[N-(SiMe(3))(2)](2)(THF)}(2), respectively, led to the formations of [Dy(mu-Cl)(dpma)(THF)(2)](2) (2) and {Yb(p-Cl)[N(SiMe(3))(2)](2)(THF)}(2) (3). Compounds 2 and 3 were fully characterized by single-crystal X-ray crystallography, elemental analysis, and (1)H NMR spectroscopy. Structure determination indicated that 2 and 3 exhibit as centrosymmetric dimers with asymmetrically bridging chloride ligands. One pot reactions involving LnCl(3) (Ln = Dy and Yb), LiN(SiMe(3))(2), and H(2)dpma were explored and desired products 2 and 3 were not yielded, which indicated that 1 and {Yb(mu-Cl)[N(SiMe(3))(2)](2)(THF)}(2) are the demanding precursors to synthesize Dysprosium and Ytterbium complexes supported by dpma(2-) ligand. Compounds 2 and 3 are the first reported lanthanide complexes chelated by dpma(2-) ligand.
