Figure 2 Part of the title crystal structure, showing the a (001) sheet with the N-H⋯O hydrogen bonds. For the sake of clarity, the H atoms bonded to C atoms have been omitted. O, N, C atoms are depicted in red, blue and black, respectively. [Symmetry codes: (i) −x + $[{1\over 2}]$ , y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (ii) −x + 1, −y, −z + 1.]
