Previous studies of kieserite analogues and also other systems (Tutton’s salts, alums and β-K2SO4 isomorphs) have shown that in a series of isostructural/isomorphous compounds the unit-cell parameters and volumes vary linearly with the eflfective ionic radii (the \u27size\u27) of the structural units. This is in line with the results of Shannon (Acta Cryst. A32 (1976) 751-767). Somewhat unexpectedly, other important parameters of the crystal structure, such as fractional atomic co-ordinates, exhibit systematic variations as well. An attempt is made to reveal the reasons that are at the origin of this finding
