Abstract

Condensation of 2,9-di(1-methylhydrazino) -1,10-phenanthroline with 2,6-pyridinedicarbaldehyde in the presence of CoII ions leads to the isolation in high yield of the seven-co-ordinate complex [Co(L1)(H2O)2]2+. The X-ray structure of the hexafluorosilicate salt has been determined. The cobalt atom is coplanar with the five-co-ordinated nitrogens of the macrocycle and has two water molecules in axial sites. The complex crystallises in space group C2/c with a = 13.739(3), b = 19.262(4), c = 12.860(4) Å, β = 121.55(3)°, and Z = 4. The structure was solved by a combination of Patterson and Fourier-difference techniques and refined to R = 0.089 for 2 153 diffractometer data.
