• A hydrous complex of erbium coordinated with glycine sodium perchloric acid, Er 2 ( μ 2 -Gly) 6 (H 2 O) 4 ·Na 2 (ClO 4 ) 8 (H 2 O) 2 ·4H 2 O (Gly = glycine), was synthesized firstly and characterized by X-ray single-crystal diffraction. The complex crystallizes centrosymmetrically in the triclinic P-1 space group [ a  = 9.2959 (5), b  = 12.1756 (7) Å, c  = 13.9928 (7) Å, V  = 1367.67 (13) Å 3 , Z  = 1]. The low-temperature molar heat capacities and thermodynamic properties of the complex were studied with adiabatic calorimetry. The thermodynamic functions, [ H T – H 298.15 ] and [ S T – S 298.15 ], were derived in the temperature range from 80 to 370 K with a temperature interval of 5 K. Thermal decomposition behavior of the complex in nitrogen atmosphere was studied by thermogravimetric analysis and differential scanning calorimetry. Graphical Abstract
