Zn(SO3)2 crystallizes in the orthorhombic Fdd2 space group. Zn(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(3) atoms. Both Zn(1)-O(1) bond lengths are 1.95 Å. Both Zn(1)-O(3) bond lengths are 1.95 Å. S(1) is bonded in a trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. The S(1)-O(1) bond length is 1.55 Å. The S(1)-O(2) bond length is 1.48 Å. The S(1)-O(3) bond length is 1.52 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one S(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one S(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Zn(1) and one S(1) atom. Linkers: 16 O=S(=O)=O. Metal clusters: 8 [Zn]. RCSR code: dia. The MOF has largest included sphere 5.63 A, density 1.22 g/cm3, surface area 3663.80 m2/g, accessible volume 0.54 cm3/g
