Abstract

While monoglyme and diglyme reacted with [YIII(hfac)3] to give eight- and nine-co-ordinate neutral complexes [Y(hfac)3(glyme)], 1 and 2 respectively, reactions with triglyme or tetraglyme resulted in disproportionation giving the ionic complexes [Y(hfac)2(glyme)]+[Y(hfac)4]–, 3a and 4 respectively; sublimation of 3a with adventitious water gave the outer-sphere glyme complex [Y(hfac)3(OH2)2]·MeO(CH2CH2O)3Me which has an infinite chain helical structure.
