Abstract
[ $BaWO_4$ ] crystals were synthesized using bidentate ligands. The reaction parameters such as the concentration of ligand and molar ratio of $[WO_4^{2-}]/[Ba^{2+}]$ played important roles in the formation of $BaWO_4$ crystals with various morphologies. When TMEDA was used as a ligand, the microrods of $BaWO_4$ crystals with length of $15{\sim}20{\mu}m$ were formed via the self assembly of cross-like plates of 250 nm in width and $2{\sim}3{\mu}m$ in length.
