Table 2. A summary of short inter­atomic contacts (Å) for (I)^a .

Contact	Distance	Symmetry operation
H2N⋯O2b	1.95	1 − x, 2 − y, 1 − z
H3O⋯N1b	1.60	1 − x, 2 − y, 1 − z
H1⋯O1	2.27	−1 + x, −1 + y, 1 + z
H6A⋯O3	2.42	−1 + x, −1 + y, 1 + z
H12⋯O1	2.34	1 − x, 1 − y, 1 − z
H14⋯O1	2.25	x, y, z
H4⋯C11	2.66	1 − x, 1 − y, 1 − z
C10⋯C10	3.28	2 − x, 2 − y, 1 − z

Notes: (a) The inter­atomic distances are calculated in Crystal Explorer 17 (Turner et al., 2017 ▸) whereby the X—H bond lengths are adjusted to their neutron values; (b) these inter­actions correspond to conventional hydrogen bonds.
