Figure 2
A fragment of the crystal structure of 2, showing the environments of the metal centres, the atom-labelling scheme for the asymmetric unit and weak hydrogen bonding (as dashed lines). Displacement ellipsoids are drawn at the 50% probability level and the H atoms of the tert-butyl groups and of the BAAP ligand bonded to C atoms have been omitted for clarity. [Symmetry codes: (i) −x + 1, −y, −z + 1; (ii) −x + 1, −y + 1, −z + 1.] |
