(a) The mol­ecular tapes in (II)[link] generated by two consecutive centrosymmetric dimers: one of them via N3—H3⋯O4i and the other via weak C12—H12B⋯O2iv hydrogen bonds. C6—H6⋯N14ii hydrogen bonds connect the tapes into sheets. Hydrogen bonds are indicated by dotted lines. [Symmetry codes: (i) −x, −y + 1, −z + 1; (ii) −x + 2, −y, −z + 2; (iii) −x, −y + 1, −z + 2.] (b) The mol­ecular tape in (II)[link], expanded along the c axis. Small steps in the tape and sheet conformations are shown.
