Bottom Line: Single crystals of monoclinic Nd(2)W(2)O(9) were obtained by growth from tungsten borate flux in an atmosphere of air.The crystal structure consists of chains of distorted [WO(6)] octa-hedra that run along the c axis of the structure, and of [NdO(9)] polyhedra that are connected via common faces and common edges to form a three-dimensional framework.

ABSTRACT
Single crystals of monoclinic Nd(2)W(2)O(9) were obtained by growth from tungsten borate flux in an atmosphere of air. The crystal structure consists of chains of distorted [WO(6)] octa-hedra that run along the c axis of the structure, and of [NdO(9)] polyhedra that are connected via common faces and common edges to form a three-dimensional framework.

View of the structure of Nd2W2O9 along the a-axis, emphasizing the arrangement and mutual connection of [NdO9] polyhedra sheets that lie parallel to the a-c plane. Nd atoms are denoted by large purple and violet spheres. Tungsten atoms (marked with smaller orange spheres) occupy interstitial space between the sheets of Nd coordination polyhedra and are arranged in layers parallel to the a-c plane. Oxygen atoms are indicated by the corners of the coordination polyhedra and are not drawn.
