Lithium-lanthanide-2-naphthoxide complexes are found to have solvent dependent solution structures and related monomeric/dimeric solid state structures. The incorporation of tetramethylguanidium cations into lanthanide 2-naphthoxide complexes stabilizes a complex structure both in solution and the solid state through bridging hydrogen bonds between the 2-naphthoxide ligands.
