The structures of [Cu(CI2H8N2)2(S406)], (I), and [Cu(CI2H8N2)3](S406).5H20, (II), are reported. Compound (I) consists of infinite polymeric chains where copper displays a typical (4+2) coordination and S406 connects Cu(phen)2 (phen is phenanthroline) units through rather long Cu...O contacts. Compound (II), instead, has a purely ionic character displaying [Cu(phen)3] 2+ and S4062- monomeric units. Equatorial and apical bonds in the copper coordination spheres have mean values of 2.003 (5)/2.467(12) and 2.056 (3)/2.311 (13),4, for (I) and (II), respectively. Some short O...OW contacts in (II) suggest the existence of hydrogen bonding involving some of the water molecules of hydration.
