摘要

The structural characterizations of the potassium complexes of a pair of dianionic bis(phenolate) ligands, {L-R = [-OC6H2(2,4-Bu-t)(6-CH2)](2)NCH2CH2R} R = NMe2, OMe, crystallized from 1,2,-dimethoxyethane (DME) are recorded, showing them to take the binuclear form [K2LR(DME)(3)]. A pair of neutral binuclear heterobimetallic isotypic complexes are defined with ytterbium(III), with phenol, as sodium salts, of the form [Yb(L-R)(OPh)(2)Na(DME)(HOPh)], and a further array with samarium(III), of the (partially protonated) form [Sm(L-OMe)(2)-Na(OH2)]. A further complex, [Na(DME)(3)][Yb(*L-py)(2)], results from an unusual ligand reduction by an ytterbium(II) species to give a new dianionic Schiff base ligand which is coordinated to ytterbium(III) {*L-py = -OC6H2(2,4-Bu-t)(6-CH=N-CH-2-C6H4N)}.
