Contact	Distance	Symmetry operation
C10⋯C14	3.345 (2)	1 − x, 1 − y, 2 − z
C12⋯C16	3.351 (2)	1 − x, 1 − y, 2 − z
O1⋯H9C	2.58	1 + x, y, z
O1⋯H14	2.61	1 − x, 1 − y, 2 − z
O3⋯H8A	2.60	−x, 1 − y, 1 − z
C5⋯H7C	2.78	1 − x, 2 − y, 1 − z
C7⋯H5	2.61	1 + x, y, z
C10⋯H8A	2.79	−x, 1 − y, 1 − z
H12⋯H9A	2.20	x, −1 + y, 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.
