Abstract: In the title compound, (C₈H₂₀N)[Co(C₂₆H₁₆N₄O₂)Cl₂], the four N atoms of the N,N'-(o-phenylene)bis(isoquinoline-2-carboxamidate) (biqb^2-) ligand form the equatorial plane of a distorted octahedral coordination environment around the Co^III ion, while two chloride ligands are axially coordinated. The Co-N_amide distances are significantly shorter than the Co-N_pyridyl distances. The dihedral angle between the two isoquinoline fused-ring systems is 25.72 (7)°. The crystal structure is stabilized, in part, by intermolecular C_cation-HCl and C_isoquinoline-HCl hydrogen bonds.
