摘要：

Nitratotetrakis(methyldiphenylarsine oxide)cobalt(II) nitrate has been described as a square-pyramidal complex with the cobalt ion in a C4 site symmetry. Despite this, the observed g values are highly anisotropic; g1 = 8.6, g2 = 1.3, and g3 =0.9. The smallest g value is found to make an angle of 12 ± 5° to the perpendicular to the basal plane. The anisotropicg values are justified by the off-axis position of the Co-O bond. A completelysymmetry independent ligand field model allowed us to rationalize the data in a simple and effective way. © 1979, American Chemical Society. All rights reserved.
