| The mean molar susceptibility (χM) for the two compounds 3,5-dibromo-p-aminobenzoic acid, Br2C6H2(p-NH2)COOH, and 3,5-dibromo-p-hydroxybenzoic acid, Br2C6H2(p-OH)COOH, has been determined. The principal molecular susceptibilities K∥ and K⊥ have been evaluated. The magnetic anisotropy of each of the two compounds was obtained. From the atonic coordinates, as given by the X-ray structure analysis of Br2C6H2(p-NH2)COOH, the crystal susceptibilities (χa, χb, and χc) have been calculated. The magnetic properties are interpreted in the light of the crystal structure. |
