Two ethylenediamine-pillared zinc hydroxysulfates related as subcell, Zn4SO4(OH)6(C2N2H 8)0.5·3H2O, and supercell, [Zn 4SO4(OH)6(C2N2H 8)0.5]7·18H2O, the zinc analogues of Co4SO4(OH)6(C2N 2H8)0.5·3H2O, were prepared and structurally characterized by single-crystal X-ray diffraction. The subcell-supercell relation is described. The analysis of hydrogen bonds and cavities were conducted, suggesting the existence of subcell-supercell to be due to a strong correlation between the organic pillars, the interlayer guests, and groups decorating the inorganic layers. Reversible dehydration-rehydration behavior on the subcell is demonstrated via thermogravimetric/differential thermal analysis and single-crystal X-ray diffraction.
