Structures of the new complexes [La(Odpp) 3 (dig)] · 0.5dig (Odpp = 2,6‐diphenylphenolate; dig = bis(2‐methoxyethyl) ether – diglyme) and [Nd(Odpp) 3 (py) 2 ] · 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.
