title: Hexaaqua-cobalt(II) 5,5'-(propane-1,3-diyldithio)bis-(1H-tetra-zole-1-acetate).
abstract: 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-tetra-zole-1-acetate) (battp(2-)) anion. The Co(II) center is coordinated by six H(2)O mol-ecules in a distorted octa-hedral coordination environment. In the crystal structure, intra- and inter-molecular O-H⋯O and O-H⋯N hydrogen bonds link the cations and anions into a three-dimensional network. π-π contacts between the tetra-zole rings [centroid-centroid distance = 3.346 (1) Å] may further stabilize the structure.
