Figure 4
A projection on to the plane of a single layer, showing the approximate rectangular arrangement of [Co(NH3)6]3+ cations, with Na+ cations between them. The [NaO5] square pyramids are viewed in projection along their axial Na1—O1W vectors, which point upwards for [NaO5] lying close to the corners of the unit cell and downwards for [NaO5] lying close to the middle of the unit cell. H atoms have been omitted. |
