title: Tetra-aqua-{1-[(1H-1,2,3-benzotriazol-1-yl)meth-yl]-1H-1,2,4-triazole}sulfato-cobalt(II) dihydrate.
abstract: In the title complex, [Co(SO(4))(C(9)H(8)N(6))(H(2)O)(4)]·2H(2)O, the Co(II) ion is six-coordinated by one N atom from a 1H-1,2,3-benzotriazol-1-yl)meth-yl]-1H-1,2,4-triazole ligand, one O atom from a monodentate sulfate ligand and four water mol-ecules in a slightly distorted octa-hedral geometry. The sulfate ligand is rotationally disordered over two sets of sites with refined occupancies of 0.662 (15) and 0.338 (15). In the crystal, complex mol-ecules and solvent water mol-ecules are linked through inter-molecular O-H⋯O and O-H⋯N hydrogen bonds into a three-dimensional network.
