Figure 1
A view of the structure of (I), showing the atom-numbering scheme and the coordination polyhedra for Ni and Ba atoms. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. [Symmetry codes: (i) −x, 1 − y, −z; (ii) 1 − x, 1 − y, −z; (iii) 1 − x, 1 − y, 1 − z.] |
