title: Tetra-kis(2-amino-pyrazine-κN)dichlorido-cobalt(II).
abstract: The Co(II) atom in the title complex, [CoCl(2)(C(4)H(5)N(3))(4)], exists in an all-trans Cl(2)N(4)Co octa-hedral geometry. The Co(II) atom lies on a special position of 2 site symmetry. Adjacent mol-ecules are linked by N-H⋯N and N-H⋯Cl hydrogen bonds into a three-dimensional network.
