摘要

Reactions of [LnCl(3)(DME)(2)] (Ln = Nd, Sin, Ho, Lu; DME = dimethoxyethane) and diglyme (diglyme = diethylen glycol dimethyl ether) in THF resulted in polymeric [LnCl(3)(diglyme)](n) (Ln = Nd (1), Sm (2)) or mononuclear complexes [LnCl(3)(diglyme)(THF)] (Ln = Ho (3), Lu (4)). Neodymium and samarium atoms in 1 and 2 are eight-coordinated by three oxygen atoms from diglyme, one terminal and four bridging chloride ions. Holmium and lutetium atoms in 3 and 4 are seven-coordinated by three oxygen atoms from diglyme, three chloride ions and one oxygen atom from THE [ErCl3(diglyme)(H2O)] (5) resulted from the reaction of ErCl3 center dot 6H(2)O, (CH3)(3)SiCl and diglyme in THE The molecular structures of 3, 4 and 5 are similar, with either a molecule of THE coordinated to the lanthanide atom in 3 and 4 or with a molecule of water coordinated in 3 and 4 or with a molecule of water coordinated in 5.
