Key indicators: single-crystal X-ray study; T = 273 K; mean (C-C) = 0.004 Å; R factor = 0.025; wR factor = 0.054; data-to-parameter ratio = 11.4. In the title compound, [Zn 2 (SO 3 ) 2 (C 10 H 8 N 2 ) 2 ], Zn 2+ and SO 3 2À form a dinuclear unit, with an inversion center at the mid-point of the ZnÁ Á ÁZn vector. Each Zn atom has distorted octahedral geometry and is coordinated by four O atoms from two SO 3 2À anions and two N atoms of the 2,2 0 -bipyridine ligand. Related literature For related
