Description

The synthesis and crystal structure of NiMoO4.nH2O were investigated. The hydrate crystallized in the triclinic system with space group P-1, Z=4 with unit cell parameters of a=6.7791(2) A, b=6.8900(2) A, c=9.2486(2) A, α=76.681(2)o, β=83.960(2)o, γ=74.218(2)o. Its ideal chemical composition was NiMoO4.3/4H2O rather than NiMoO4.1H2O. Under hydrothermal conditions the hydrate turned directly into α-NiMoO4 above 483 K, giving nanorods thinner than the crystallites of the mother hydrate. On the other hand, it turned into Anderson type of polyoxomolybdate via a solid-solution process in a molybdate solution at room temperature. - Graphical abstract: NiMoO4.nH2O crystallized in the triclinic system with space group P-1, and its ideal chemical composition was NiMoO4.3/4H2O rather than NiMoO4.1H2O.
