X-ray powder diffraction data, unit-cell parameters, and space group for deferasirox, C21H15N3O4, are reported [a = 8.821(7) Å, b = 26.798(2) Å, c = 7.540(4) Å, α = 90°, β = 94.655(2)°, γ = 90°, unit-cell volume V = 1776.7(3) Å3, Z = 4, ρcal = 1.396 g cm−3, and space group P21/c]. All measured lines were indexed and are consistent with the P21/c space group. No detectable impurity was observed.
