HYDROTHERMAL SYNTHESIS OF COPPER MOLYBDATES Academic Article uri icon

abstract

  • Several copper molybdate phases were prepared either hydrothermally or by reflux reactions at ambient pressures. Cu4Mo6O20was obtained by the hydrothermal reaction of CuO and Mo03 in H20. It is triclinic, space group P1 with a = 10.071 (4) , b = 9.796 (6) , c = 8.052 (4) , a = 104.98 (4), = 100.63 (4), = 82.91 (4), and Z = 2. The structure consists of chains of edge-sharing Mo06 octahedra with the copper ions residing between the chains. Cu3(MoO4)2(OH)2 was prepared through precipitation from the reaction of CuSO4.5H2O and Na2MoO4.2H2O. The same product formed hydrothermally when CuO and Mo03 were treated in aqueous sodium molybdate. The use of NaOH in hydrothermal reaction led to the formation of NaCu(OH)(MoO4), which is isomorphous with the zinc phase previously reported. Hydrothermal treatment of Cu3(MoO4)2(OH)2 in sodium molybdate also resulted in the formation of the latter phase. 1986, American Chemical Society. All rights reserved.
