Transition metal--phtahalocyanine (Pc) compound, TPP[Fe(Pc)(CN)2]2, which is one of molecular conductors of charge transfer type with 3/4-filled conduction band consisting of LUMO of Pc molecules, shows characteristic features in transport and magnetic properties resulting from localized magnetic moments S=1/2 associated with Fe+3 atoms. We construct an effective tight-binding model of this system and study the mechanism of exchange interaction, J, between d and \pi electrons based on both second order perturbation of transfer integrals between d and \pi orbitals and numerical diagonalization. It is found that there is no hybridization between d-orbitals and LUMO of \pi-orbitals and then super-exchange interaction in the Anderson model does not exist. Instead, processes associated with Hund's rule both on d and \pi orbitals, which may be called ``the double Hund's exchange mechanism'', turn out to play important roles and the sign of resultant J can be either ferromagnetic or antiferromagnetic depending on model parameters because of competition among various processes. By taking account of magnetic anisotropy due to spin--orbit interactions and comparing with experimental results, it is indicated that J is antiferromagnetic and of the order of 100 K.
