Crystal structure of copper hydroxynitrite Cu 2 (OH) 3 (NO2)

Résumé

The crystal structure of Cu2(OH)3(NO2) has been determined by single crystal technique. Data were collected from X-ray diffractometer and the structure was refined by least squares method to a final R index of 4.4% (Rw = 6.2%) from 732 reflections with I > 4s(I). The crystal structure can be roughly described in the monoclinic space group P21 /m, but crystals are really triclinic (space group: P-l): a = 5.609(3), b = 6.039(6), c = 6.622(3) Å, a = 90.07(6), b = 95.43(4), g = 89.99(6)°, V = 223.3 Å 3 , Z = 2, d calc = 3.33, d obs = 3.3 g.cm-3. The structure of this hydroxysalt is built up by octahedral layers containing all the Cu 2+ ions. The interlayer space is occupied by the nitrite group, characterized by a phenomenon of disorder involving one of its oxygens. The linkage between the successive layers is just due to strong hydrogen bonds.
