Synthesis and crystal structure of catena-poly[cobalt(II)-di-μ-chlorido-μ-pyridazine-κ²N¹:N²].

ABSTRACT: The reaction of cobalt dichloride hexa-hydrate with pyridazine leads to the formation of crystals of the title compound, [CoCl₂(C₄H₄N₂)]_n. This compound is isotypic to a number of compounds with other divalent metal ions. Its asymmetric unit consists of a Co²⁺ atom (site symmetry 2/m), a chloride ion (site symmetry m) and a pyridazine mol-ecule (all atoms with site symmetry m). The Co²⁺ cations are coordinated by four chloride anions and two pyridazine ligands, generating trans-CoN₄Cl₂ octa-hedra, and are linked into [010] chains by pairs of μ-1,1-bridging chloride anions and bridging pyridazine ligands. In the crystal structure, the pyridazine ligands of ne
