N 2-(2-Pyrid­yl)-N 6-(4-pyrid­yl)pyridine-2,6-diamine

In the title compound, C15H13N5, the dihedral angles between the central aromatic ring and and the two peripheral rings are 1.5 (6) and 33.1 (4)°. In the crystal, inter­molecular N—H⋯N hydrogen bonds connect the mol­ecules into a zigzag chain propagating in [100]

catena-Poly[[dichloridocobalt(II)]-μ-1,2-di-4-pyridylethane-κ2 N:N′]

In the title compound, [CoCl2(C12H12N2)], the CoII atom is coordinated in a tetra­hedral geometry by the N atoms of two different 1,3-di-4-pyridylpropane ligands. The compound adopts a linear chain structure
