A new compound, Pb3OBO3F, has been grown by the high temperature solution method from the PbO-PbF2-B2O 3 system. It crystallizes in the orthorhombic system, space group Pbcm with unit-cell parameters a = 7.6313(14) , b = 6.5229(12) , c = 11.906(2) , Z = 4, volume = 592.66(19) 3. The structure of the compound is solved by the direct methods and refined to R1 = 0.0528 and wR 2 = 0.1400. Pb3OBO3F consists of Pb(1)O 3F tetrahedra, Pb(2)O4 tetrahedra and BO3 triangles which build up the symmetrical chains extended along the c-axis. The powder X-ray diffraction pattern of the Pb3OBO3F has been measured. Functional groups presented in the sample were identified by Fourier transform infrared spectrum.
