Figure 3
A packing diagram (DIAMOND; Bergerhoff et al., 1996) for bis(glycine) nickel(II) dibromide dihydrate (top) compared with bis(glycine) cobalt dichloride dihydrate (bottom). Both structures are viewed along [010]. The layers are oriented vertically. For the purposes of comparison, the unit cell of the bromide structure is superimposed on the chloride structure (grey lines). To observe the difference between the two compounds notice the orientation of the octahedra. |
