Diagram showing the two molecules (A and B) linked by a bifurcated hydrogen bond between the N3A—H3A group and atoms O3B and N2B, and further linked into a ribbon along the a-axis direction by a bifurcated hydrogen bond between the N3B—H3B group and atoms O3A and N2A (generated by the symmetry operation x + 1, y, z). |
