Poly[[(1,10-phenanthroline){μ(3)-2,2′,2′′-[1,3,5-triazine-2,4,6-triyltris(sulfane­diyl)]triacetato}­cadmium] 0.42-hydrate]

The asymmetric unit of the title complex, {[Cd(C(9)H(7)N(3)O(6)S(3))(C(12)H(8)N(2))]·0.42H(2)O}(n), contains a Cd(II) atom, one doubly deprotonated 2,2′,2′′-[1,3,5-triazine-2,4,6-triyltris(sulfanediyl)]triacetic acid ligand (HTTTA(2−)), a 1,10-phenanthroline (phen) ligand and a fractionally occupied water mol­ecule [site occupancy = 0.421 (15)]. The Cd(II) atom is six-coordinated within a distorted octa­hedral coordination geometry. Six coordination arises from four O atoms derived from three different HTTTA(2−) ligands, and two N atoms of the chelating phen mol­ecule. The incompletely deprotonated triazine ligand adopts a μ(3)-η(1):η(1):η(2) coordination mode, resulting in the formation of chains along the c axis based on Cd(2)O(2) dimeric units. Adjacent chains are stacked through π–π stacking [3.533 (2) Å between phen and triazine rings] and C—H⋯O inter­actions, forming supra­molecular sheets in the ab plane. Intra-and intermolecular O—H⋯O hydrogen bonds are also observed.
