Figure 1
A fragment of the crystal structure of 1, 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 code: (i) −x + 2, −y + 1, −z + 1.] |
