The title compound is a novel yellow pyrazolyl azo pigment used in imaging industries. This compound crystallizes in a triclinic system, as characterized by the following crystallographic parameters: P1, a = 6.7561(12), b = 14.054(2), c = 16.203(3)Å, α = 83.924(6), β = 83.276(7), γ = 79.140(7)°, Z = 2, V = 1495.0(4)ų. The structure was solved by direct methods and refined by full-matrix least-squares on F² to final values of R1 = 0.1373 and wR2 = 0.3346.
