The structure of the title compound, [Co(C5H5N)2(H2O)4](C10H8ClN4O2S)2, consists of a discrete tetraaquabis(pyridine-κN)cobalt(II) cation and two 4-amino-N-(6-chloropyridazin-3-yl)benzenesulfonamidate anions. In the cation, the CoII ion sits on an inversion centre and is octahedrally coordinated by two pyridine N atoms and four O atoms. A two-dimensional network parallel to (010) is formed via intermolecular O—H⋯O, O—H⋯N, N—H⋯N and N—H⋯O hydrogen bonds.

Samples of sulfachloropyridazine (0.2 mmol) and Co(Ac)2.4H2O (0.1 mmol) were placed in a thick-walled Pyrex tube (ca 20 cm long). After addition of ethanol (2.2 ml), H2O (0.2 ml) and pyridine (0.1 ml), the tube was frozen with liquid nitrogen, evacuated under vacuum and sealed with a torch. The tube was heated at 80°C for 3 days and then was slowly cooled down to room temperature, and orange-yellow block-shaped crystals were obtained. Yield: 80%.
The H atoms bonded to C atoms were positioned geometrically and refined using a riding model with Uiso(H) = 1.2Ueq(C) (C—H = 0.95 Å). The H atoms attached to amino N were placed in the calculated positions, with N—H distance of 0.88 Å. The Uiso(H) values were constrained to be 1.2Ueq of the
for amino H atom. H atom attached to O was located in an electron-density difference map and refined isotropically.Data collection: CrystalClear (Rigaku, 1999); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Sulfachloropyridazine [4-amino-N-(6-chloro-3-pyridazinyl)-benzensulfonamide], is a synthetic sulfanilamide antibacterial drug whose crystal structure is known (Tan et al. 2005). However, as far as we are aware, no crystal structure of a metal complex containing sulfachloropyridazine has been published, although the electrochemistry of its copper(I) complex has been described by Fogg et al. (1995). The compound consists of a [Co(H2O)4(py)2]2+ cation and two sulfacholoropyridazine anions. Similar to tetraaquabis(pyridine-κN)cobalt(II) diacetate (Clegg et al., 2006), the coordination geometry for the CoII cation (Fig. 1) is close to an ideal octahedron (N1—Co1—N1#1 180.000 (1)°, O1—Co1—O2 92.37 (9)°, O1—Co1—O2#1 87.63 (9)°, #1: -x + 2,-y + 1,-z + 1), with the O atoms of the coordinated water molecules occupying the equatorial positions and with the axial sites occupied by coordinated pyridine ligands. The sulfachloropyridazine is depronated at sulfamide N2 to generate anions, whose geometric parameters are comparable to sulfachloropyridazine (Tan et al., 2005). A two-dimensional network is formed via intermolecular hydrogen bonds of type O—H···O, O—H···N and N—H···O (Table 1).
