Crystal growth and structure of KBi(WO4)2 single crystals

Abstract

Potassium bismuth tungstate [KBi(WO4)2] single crystals have been grown by the top-seeded solution growth technique. Bulk crystal with dimensions up to several centimeters is obtained for the first time. Several self-flux systems have been used for the growth from the solution and the experiments using K2W2O7 as a solvent are detailed. Powder and single crystal X-ray diffraction of this crystal are reported. The structure refinement shows that KBi(WO4)2 crystallizes in the monoclinic space group C2/c, with a=10.837(3), b=10.586(3), c=7.622(2)Å, β=130.860(3)°, V=661.4(3)Å3, and Z=4. © 2006 WILEY-VCH Verlag GmbH & Co.
