ResumoA new lead borate, Pb[B8O11(OH)4], has been hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction, FTIR, powder X-ray diffraction and thermogravimetric analysis. The compound crystallizes in the monoclinic system, space group P21/n (No. 14), a=7.9081(2)Å, b=14.0248(3)Å, c=9.9910(3)Å, β=90.327(2)°, V=1108.08(5)Å3, and Z=4. The structure consists of layers of 9-membered borate rings enclosing Pb2+ cations. Adjacent borate layers are interconnected via ionic Pb–O bonds and hydrogen bonding to form a 3D supramolecular network.
