(a) The infinite one-dimensional chains of (I), propagating along the [001] direction, (b) the stacking of the chains of (I), (c) the infinite one-dimensional chains of (II), propagating along the [001] direction, and (d) the stacking of the chains of (II). Classical N—H⋯O and nonclassical C—H⋯O hydrogen-bond interactions are shown as dashed lines. [Symmetry codes, (a): (i) −x + 1, −y + 1, −z; (ii) −x + 1, −y + 1, −z + 1; (c): (i) x, −y + , z − ; (ii) x, −y + , z + .] |
