ORTEPII (Johnson, 1976) drawings of the complexes (1b) and (2b) with atom numbering. The displacement ellipsoids for the non-H atoms are drawn at 50% probability and the H atoms are drawn as spheres with a radius of 0.1 Å. (a) (1b), symmetry codes: (i) ; (ii) . (b) (2b), symmetry codes: (i) ; (ii) . |
