Fragment of the crystal packing of (I), viewed along the b-axis direction, showing intermolecular N—H⋯N/O and O—H⋯O interactions (CH hydrogen atoms were omitted for clarity; hydrogen bonds are shown as blue dashed lines; green lines joining Ni centres do not represent bonds). [Symmetry codes: (i) −x + 2, −y + 2, −z + 1; (ii) −x + 2, −y + 1, −z + 1.] |
