Figure 3
The second-sphere coordination of the [Co(NH3)6]3+ cation in (I). The CO2− group containing atoms O1 and O2 forms an edge-to-face interaction, while the other three interactions shown are vertex-to-face. Atom Co1 lies on a centre of inversion so that a comparable arrangement is formed on the opposite side of the plane (not shown). H atoms have been omitted.
