Abstract
Measurements of the crystal diamagnetic susceptibilities of isomorphous trihalogenbenzenic crystals C6H3X3 (X = Cl, Br) of orthorhombic structure are reported. Molecular components, as diagonal values in crystal molecular tensor relation are deduced and their variancies are discussed. The measurements show that the molecular structure of these related crystals is of layer type, the molecules being planar in the vicinity of the (001) plane. Effects of partial substitution of halogen ions on the magnetic properties and on the packing forces of these crystals are also discussed. Reduction of the molecular anisotropies were observed and reduction of the molecular orbital areas were expected.
