Abstract

The reaction of cobalt(II) chloride with 2,3,5,6-tetra(2-pyridyl)pyrazine (tppz) in the presence of sodium chloride gives polynuclear complexes; recrystallisation from acetonitrile yields a linear polymer containing three different types of cobalt(II) environment. This compound, [{(μ-Cl)2(MeCN)Co(tppz)Co(CoCl4)}n], has been structurally characterised (orthorhombic, P212121, a = 12.967(3), b = 14.624(3), c = 18.043(4) Å, V = 3421.5(13) Å3, Z = 4, R 1 = 0.0584, wR2 = 0.1868).
