Solid State and Solution Structures of Lanthanide Nitrate Complexes of Tris-(1-napthylphosphine oxide).

ABSTRACT: Coordination complexes of lanthanide metals with tris-1-naphthylphosphine oxide (Nap₃PO, L) have not been previously reported in the literature. We describe here the formation of lanthanide(III) nitrate complexes Ln(NO₃)₃L₄ (Ln = Eu to Lu) and the structures of [Ln(NO₃)₃L₂]·2L (Ln = Eu, Dy, Ho, Er) and L. The core structure of the complexes is an eight-coordinate [Ln(NO₃)₃L₂] with the third and fourth ligands H-bonded via their oxygen atoms to one of the naphthyl rings. The structures are compared with those of the analogous complexes of triphenylphosphine oxide and show that the Ln-O(P) bond in the Nap₃PO complexes is slightly longer than expected on the basis of differ
