Title: Crystal structure of cobalt molybdate hydrate CoMoO{sub 4}.nH{sub 2}O

Abstract

We have determined the crystal structure of the title compound, which has a triclinic cell with cell parameters of a=6.844A, b=6.933A, c=9.339A, {alpha}=76.617{sup o}, {beta}=84.188{sup o}, {gamma}=74.510{sup o} and space group P1-bar. The crystal structure suggests the chemical formula CoMoO{sub 4}.3/4H{sub 2}O. The structure consists of MoO{sub 4} tetrahedra and CoO{sub 6} 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 {alpha}-,{beta}-, and hp-phases shows that the hydrate exhibits metal cation coordinations similar to those of the {beta}-phase, but had arrangements of CoO{sub 6} and MoO{sub n} polyhedra similar to those of the hp-phase.
