Abstract

Structures of the new complexes [La(Odpp)(3)(dig)]center dot 0.5dig (Odpp = 2,6-diphenylphenolate; dig = bis(2-methoxyethyl) ether - diglyme) and [Nd(Odpp)(3)(py)(2)]center dot 2py (py = pyridine), obtained by crystallization of the corresponding [Ln(Odpp)(3)(thf)(2)] complex from diglyme or pyridine contain six-coordinate and five-coordinate lanthanoid atoms respectively. In the former, two meridional sets of donor atoms, (O-3(dig) and O-3(Odpp)) are near normal to each other and in a highly distorted octahedral stereochemistry, whereas the latter is trigonal bipyramidal with an oxygen and a nitrogen atom apical and a pronounced lengthening of the axial Nd-N bond.
