The reaction of PbO with cyanuric acid was reported to give lead cyanurate, described in the literature as Pb3(O3C3N3)2·2H2O. Crystalline powders were prepared and investigated by X-ray powder diffraction, yielding a monoclinic crystal structure (space group Cc, a = 16.6217(1) A, b = 6.7161(1) A, c = 12.4308(1) A, β = 117.567(1)°). The structure solution and refinement yielded lead oxide isocyanurate corresponding to the formula Pb3O2(O3C3N3H2)2, with a layered arrangement of [Pb3O2]2+ ions and monovalent isocyanurate anions in an alternating fashion. |
