Cobalt(II) nitrate hexa­hydrate and sodium dicyanamide self-assembled in dimethyl­formamide (DMF) and 4-methyl­pyridine solutions to form the title compound, [Co(C2N3)2(C6H7N)2]n. The Co2+ ion lies on an inversion center and adopts an octa­hedral coordination geometry in which four N atoms from four different dicyanamide ligands lie in the equatorial plane and two 4-methyl­pyridine N atoms occupy the axial positions. The CoII atoms are connected by two bridging dicyanamide ligands, resulting in a chain parallel to the c axis. The chains are connected into a three-dimensional network by C—H...N hydrogen bonds.

The title compound, C28H38Br2N2, is centrosymmetric with the mid-point of the central C-C bond of the butyl group located on an inversion center. The terminal benzene ring is approximately perpendicular to the central 1,4-diaza­butadiene mean plane [dihedral angle = 78.23 (3)°]. No hydrogen bonding or aromatic stacking is observed in the crystal structure.
