Figure 1
The extended asymmetric unit in I showing the coordination environment of the Ni atoms and the atom-labelling scheme (displacement ellipsoids are drawn at the 40% probability level). C-bound H atoms are omitted for clarity. Dotted lines represent hydrogen-bonding inter­actions. Symmetry codes: (i) −x + 1, −y + 1, −z; (ii) −x, −y + 2, −z; (iii) x − 1, y + 1, z; (iv) −x + 1, −y, −z + 1; (v) −x, −y + 1, −z + 1.
