The crystal structures of bis(2,2'-bipyridyl)(saccharinato-N)copper(II) saccharinate dihydrate [Hergold-Brundic et al. (1991). Acta Cryst. C47, 2659-2660] and bis(2,2'-bipyridine)(saccharinato-N)copper(II) saccharinate trihydrate [Li et al. (1991). Polyhedron, 10, 403-407] are compared. It is concluded that it is likely that they are actually the same compound and that the reported water content in the trihydrate is in error.
