Abstract

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 P1̄. The crystal structure suggests the chemical formula CoMoO₄·3/4H₂O. The structure consists of MoO ₄ 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 MoO_n polyhedra similar to those of the hp-phase.
