چکیده انگلیسی
We have determined the crystal structure of the title compound, which has a triclinic cell with cell parameters of a=6.844Å, b=6.933Å, c=9.339Å, α=76.617°, β=84.188°, γ =74.510° and space group P1¯. The crystal structure suggests the chemical formula CoMoO4·3/4H2O. The structure consists of MoO4 tetrahedra and CoO6 octahedra, confirming the earlier X-ray absorption near-edge spectroscopic (XANES) investigation on the hydrate. The comparison of the crystal structures of the hydrate and the α-,β-, and hp-phases shows that the hydrate exhibits metal cation coordinations similar to those of the β-phase, but had arrangements of CoO6 and MoOn polyhedra similar to those of the hp-phase.
