Molecular neodymium and yttrium cations with the N,N-Bis[2-(pyrid-2-yl) ethyl]hydroxylaminato ligand

摘要

The three component reaction of LnCp_3, LnCp_2Cl (Ln = Nd, Y) and N,N-bis[2-(pyrid-2- yl)ethyl]hydroxylamine [HON(C2H4-o-py)2] results in the formation of the [Nd(ON(C2H4-opy) 2)_2]~+[NdCp _3Cl]- salt in the case of neodymium and the [Y(ON(C_2H _4-o-py)_2)_2]~+[YCp_2Cl _2]- salt if yttrium is used in the synthesis. The N,N-bis[2-(pyrid-2-yl)ethyl]hydroxylaminato ligand is able to coordinate doubly to the metal atoms resulting in the formation of a cationic species. The compounds were characterised by X-ray diffraction experiments and additionally by CHN analyses in the case of the neodymium salt.
