Özet

The magnetic moments of a Co(II) complex in a recently reported CoL(2)(.)5H(2)O compound (L is 5-chloro-2-methoxybenzoate, ClC6H3(OCH3)COO-) were studied by a semi-theoretical approach in the vicinity of tetragonal distortion. It was found that in order to obtain the observed temperature-dependent magnetic moments, some parameters in the magnetic Hamiltonian which are related to the geometry of the complex should be varied. Comparing the calculated results of this study with experimental results from the literature, a distorted octahedral environment of Co(II) ion in the compound is predicted. Also, rather high probability of large orbital contribution to the magnetic moment is expected. Some abnormalities in previously reported data might be reduced by taking the experimental data with VSM (Vibrational Susceptibility Magnetometer).
