Fig. 1. The asymmetric unit of (I) and selected symmetry-equivalent atoms, showing the coordination of both metal ions and ligands. Displacement ellipsoids are drawn at the 40% probability level and H atoms have been omitted for clarity. [Symmetry codes: (i) 1 − x, −y, −z; (ii) 1 − x, −y, 1 − z; (iii) x, − y, + z; (iv) x, − y, − + z]. |
