摘要：

Approximately projected unrestricted Hartree-Fock (APUHF) STO-3G and 4-31G calculations have been carried out for charge-transfer (CT) complexes with radical substituents. The computations reveal that the signs of intermolecular effective exchange integrals are variable with stacking modes of donor-acceptor pairs. Organic ferromagnets and/or ferrimagnets are conceivable for appropriately stacked CT complexes with radical groups. The calculated results are also discussed in relation to possibilities of conversions of CT complexes into organic magnetic conductors such as ferromagnetic metal. © 1990.
