Er2(CO3)2(C2O4)(H2O)2 — Synthese,Kristallstruktur und thermischer Abbau eines Carbonat‐Oxalat‐Hydrates des Erbiums

Er₂(CO₃)₂(C₂O₄)(H₂O)₂ — Synthesis, Crystal Structure and the Thermal Decomposition of a Carbonate‐Oxalate‐Hydrate of Erbium The hydrothermal reaction of an equimolar ratio of Er₂O₃ with the aminoacid L‐cysteine in evacuated glass ampoules in H₂O at 130 °C gave transparent, pink crystals of the formula Er₂(CO₃)₂(C₂O₄)(H₂O)₂. It crystallises in the monoclinic space group Cm (Z = 2, a = 777.3(2) pm, b = 1492.0(3) pm, c = 473.09(8) pm, b = 90.12(9)°). The thermal decomposition of Er₂(CO₃)₂(C₂O₄)(H₂O)₂ was investigated.
