X-ray diffraction - Opis:
- The single crystals of perfectly quality of the diammonium oxalate monohydrate, [NH4]2[C2O4][H2O], were obtained by the improved methods of crystal growth from solution. The crystal structure of title compound was studied at 150 K using modern X-ray equipment. At this temperature, as well as at room temperature, this compound crystallizes in the orthorhombic symmetry wiith P21212 space group. The unit cell of the title compound is formed by four amonium cations, two oxalate anions and water molecules, with a 2:1:1 cation-anion-water ratio. At 150 K oxalate ion is twisted by 26.9 (1)°. The similar twist angle (26.6 (4)° was observed at the room temperature. Central carbon-carbon bond in oxalate ion is insignificantly longer (1.568 Å) in comparing with this bond at room temperature (1.559 Å).
