N2 - Reaction of 2,2′-iminobisbenzaldehyde with 2,9-di(1-methylhydrazino)-1,10-phenanthroline in the presence of cobalt(II) ions and pyridine leads to the formation of the spin-free title complex [CoL3(py)2]+ (py = pyridine). The X-ray structure of the tetraphenylborate salt confirms a seven-co-ordinate, distorted pentagonal-bipyramidal geometry for the metal ion, which is bound equatorially by five nitrogens from the macrocycle and has two pyridine molecules in the axial sites. The complex crystallises in space group P21/n with a = 16.786(4), b = 23.034(4), c = 13.546(3) Å, β = 97.09(3)°, and Z = 4. The structure was solved by Patterson and Fourier-difference techniques and refined to R = 0.097 and R′ = 0.079 for 2 458 observed reflections.
