Abstract
The body of research on organic radical crystals is extended with an investigation of the magnetic characteristics of eight kinds of 3-(4-R-substituded-phenyl)-1,5-diphenyl-6-oxo and -thioxoverdazyl radicals (R = OCH(sub 3), CH(sub 3), CN and NO(sub 2)). The ferromagnetic intermolecular exchange interactions had high probability for the verdazyl radical crystals, which allowed ab initio molecular orbital calculations. Findings revealed a very strong spin polarization effect, which facilitates the intermolecular ferromagnetic interaction.
