    • The indirect interaction which may occur in molecular systems differs from that occurring in the inorganic classical metals in the following points: (1) Most often the interaction between localized and conduction electrons is intermolecular, and thus weak, and involves a d-π exchange interaction, while in the inorganic metals this interaction is intra-atomic, and thus quite strong, and involves a direct interaction between localized 3d or 4f electrons and the delocalized conduction electrons (which are mainly of s character). (2) The electron correlation effects are much more important in the molecular metals than in the inorganic ones, and, therefore, the RKKY free electron model may be a too rude approach to account for the indirect exchange interactions in these hybrid molecular materials.
