Figure 4
Selected stereochemical parameters of kieserite-type compounds M2+SO4·H2O (M2+ = Mg, Fe, Co, Ni) in the temperature range 15–313 K with second-order regression lines. (a) Individual and mean M—O bond lengths, (b) O3—H⋯O2 hydrogen bond lengths, (c) M—O—S and M–O3–M angles at polyhedra-linking oxygen atoms, and (d) rotations of tetrahedral O1—O1′ and O2—O2′ edges relative to those in the Mg compound at 293 K. For errors see the underlying structural data in Tables S1, S2 and S3.
