title: Tetra-aqua-bis(pyridine-κN)cobalt(II) bis-[4-amino-N-(6-chloro-pyridazin-3-yl)benzene-sulfonamidate].
abstract: The structure of the title compound, [Co(C(5)H(5)N)(2)(H(2)O)(4)](C(10)H(8)ClN(4)O(2)S)(2), consists of a discrete tetra-aqua-bis(pyridine-κN)cobalt(II) cation and two 4-amino-N-(6-chloro-pyridazin-3-yl)benzene-sulfonamidate anions. In the cation, the Co(II) ion sits on an inversion centre and is octa-hedrally coordinated by two pyridine N atoms and four O atoms. A two-dimensional network parallel to (010) is formed via inter-molecular O-H⋯O, O-H⋯N, N-H⋯N and N-H⋯O hydrogen bonds.
