We have grown single crystals of BaH2SiO4 by hydrothermal method. The crystal structure has been studied by direct method. Based on the 1792 unique reflections collected using MoKα of X-ray radiation and a CCD-based detector, it is refined to an agreement index (R1) of 6.36%. The cell is triclinic with dimensions: a = 7. 0790, b = 7. 3620, c = 7. 5824 and α = 89. 640°, β = 88. 785°, γ = 88. 230°. There are four unit cells of BaH2SiO4 in the cell, with space group P-1.
