The magnetic moment of the Co2+ stop ion in the newly reported macrocycle complex is analysed for various situations. It is realized that in order to obtain the observed magnetic moment, either some irrelevant parameters or some intermolecular antiferromagnetic interactions must be included in the magnetic Hamiltonian. It is suggested that the complex behaves as a largely distorted octahedron.
