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.
