Hexaaqua­cobalt(II) 5,5′-(propane-1,3-diyldithio)bis­(1H-tetra­zole-1-acetate)

The asymmetric unit of the title complex, [Co(H(2)O)(6)](C(9)H(10)N(8)O(4)S(2)), contains one-half of a [Co(H(2)O)(6)](2+) cation and one-half of a 5,5′-(propane-1,3-diyldithio)bis­(1H-tetra­zole-1-acetate) (battp(2−)) anion. The Co(II) center is coordinated by six H(2)O mol­ecules in a distorted octa­hedral coordination environment. In the crystal structure, intra- and inter­molecular O—H⋯O and O—H⋯N hydrogen bonds link the cations and anions into a three-dimensional network. π–π contacts between the tetra­zole rings [centroid–centroid distance = 3.346 (1) Å] may further stabilize the structure.
