The structure of Nb2Mo3O14double oxide is refined from powder data using synchrotron radiation and the anomalous scattering effect; space groupP21mis found for the material. It is demonstrated that in the tetragonal unit cell with parametersa= 23.173 Å,c= 4.0027 Å Nb5+and Mo6+ions are stochastically distributed in MO6octahedra and MO7pentagonal bipyramids of the polygonal network structure of the Mo5O14type.
