Abstract
While monoglyme and diglyme reacted with [Y-III(hfac)(3)] to give eigh t-and nine-co-ordinate neutral complexes [Y(hfac)(3)(glyme)], 1 and 2 respectively, reactions with triglyme or tetraglyme resulted in dispro portionation giving the ionic complexes [Y(hfac)(2)(glyme)](+)[Y(hfac) (4)](-), 3a and 4 respectively; sublimation of 3a with adventitious wa ter gave the outer-sphere glyme complex [Y(hfac)(3)(OH2)(2)]. MeO(CH2C H2O)(3)Me which has an infinite chain helical structure.
