Zn(SO4)2 crystallizes in the tetragonal I-42d space group. Zn(1) is bonded to four equivalent O(1) atoms to form ZnO4 tetrahedra that share corners with four equivalent S(1)O4 tetrahedra. All Zn(1)-O(1) bond lengths are 1.94 Å. S(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SO4 tetrahedra that share corners with two equivalent Zn(1)O4 tetrahedra. Both S(1)-O(1) bond lengths are 1.48 Å. Both S(1)-O(2) bond lengths are 1.44 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a single-bond geometry to one S(1) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one S(1) atom. Linkers: 8 [O]S([O])(=O)=O. Metal clusters: 4 [Zn]. RCSR code: dia. The MOF has largest included sphere 5.11 A, density 1.32 g/cm3, surface area 3673.89 m2/g, accessible volume 0.45 cm3/g
