Figure 4
Part of the crystal structure of (III

), showing the formation of a chain of edge-fused rings along [01 $[\overline 1]$ ]. For the sake of clarity, the unit-cell box and the water ligands have been omitted, as have H atoms bonded to C atoms. Atoms marked with an asterisk (*), hash (#), dollar sign ($), ampersand (&) or plus sign (+) are at the symmetry positions (1 − x, 1 − y, 1 − z), (1 −x, 2 − y, −z), (x, 1 + y, z − 1), (x, y − 1, 1 + z) and (1 − x, −y, 2 − z), respectively.
