Figure 2 Partial packing view of the title compound, showing the formation of $[R_{2}^{2}]$ (10) (A1) and $[R_{2}^{2}]$ (8) (A2) rings through N—H⋯N, N—H⋯O, N—H⋯F and O—H⋯F hydrogen bonds. For the sake of clarity, H atoms not involved in hydrogen bonding have been omitted. [Symmetry codes: (i) −x, y − $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (ii) −x, y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (iii) x, y − 1, z; (iv) −x, −y, −z + 1.].
