The crystal structure of [Lu(HOCH 2 COO) 2 (H 2 O) 4 ][Lu(HOCH 2 COO) 4 ] ( 1 ) and Dy 2 (OCH 2 COO) 2 (HOCH 2 COO) 2 · 4H 2 O ( 2) were determined by X‐ray crystallography. The space group of 1 and 2 are P2/c and P2 1 /c, respectively. In 1 , discrete anions and cations held together by hydrogen bonds form the lattice, while the structure of 2 is a 3‐D network of cross‐linked metal‐ligand chains. The lanthanides are eight‐coordinated by chelating glycolate ligands and water molecules with distorted dodecahedral coordination. The core of 2 is a centrosymmetric dimer complex formed by two dysprosium atoms bridged by two oxygen atoms from deprotonated hydroxyl groups of glycolate ligands. The vibration spectra of the crystals were also measured and compared to each other.
