Abstract

Neodymium(III) ortho-oxidotungstate(VI) was synthesized as a side-product in an unsuccessful synthesis attempt at fluoride derivatives of neodymium tungstate in fused silica ampoules, using neodymium(III) oxide, neodymium(III) fluoride and tungsten trioxide. Violet, platelet-shaped single crystals of the title compound emerged of the bulk, which crystallize in the defect scheelite type with a trigonal dodeca-hedral coordination of oxide anions around the Nd3+ cations and the hexa-valent tungsten cations situated in the centers of oxide tetra-hedra.

Keywords: crystal structure; neodymium; oxidotungstate(VI); scheelite.
