Cover illustration: The structural model of Dy2(MoO4)3, viewed along the b axis. Tetrahedra are formed by Mo atoms and polyhedra by Dy atoms. See Dorzhieva, Chumak, Sarapulova, Mikhailova, Bazarova & Ehrenberg [Acta Cryst. (2011), C67, i50-i52].
The single crystals of the tetragonal modification of dysprosium orthomolybdate obtained in the present work are stable at room temperature. The crystal structure is formed by corner-sharing MoO4 tetrahedra and Dy polyhedra coordinated by seven O atoms.
