1H-Benzotriazol-3-ium (1H-benzotriazole-κN 3)trichloridocobaltate(II) monohydrate: a reformulation

چکیده
The asymmetric unit of the title compound, (C(6)H(6)N(3))[CoCl(3)(C(6)H(5)N(3))]·H(2)O, contains two crystallographically independent cations, two anions and two water mol-ecules. The structure has been reported previously [Zhang, Li, Wang, Xie, Wang & Shen (2004 ▶). Acta Cryst E60, m498-m500] as a neutral cobalt(III) complex accompanied by unprotonated benzotriazole mol-ecules and here has been redetermined as an anionic cobalt(II) complex accompanied by protonated benzotriazole cations. For both complex anions, a tetra-hedral CoNCl(3) geometry arises. A network of N-H⋯O, N-H⋯Cl, O-H⋯O and O-H⋯Cl hydrogen bonds helps to establish the packing.
