S. W. Ng

Abstract: The space group of the title compound, [Zn(C₁₀H₈N₂)₂(H₂O)₂](C₆H₂N₃O₇)₂·2H₂O, reported as Cc [Liang et al. (2001). Chin. J. Inorg. Chem. 17, 699-703], is revised to C2/c. In the revised description, the Zn atom lies on a special position of 2 symmetry (Wyckoff 2e); one 4,4'-bipyridine entity also lies on a twofold axis that passes through the two N atoms, whereas the other 4,4'-bipyridine entity lies on an inversion center (Wyckoff 4a) that lies midway between the 4- and 4'-C atoms.
