The Chevrel-phase compounds PbMo6S8 and Cul.8Mo6S8 have been investigated by tunneling spectroscopy. These superconductors show a very strong electron-phonon interaction expressed by 4 <--2Ao/kTc<--5. Structures in the tunneling density of states have been observed at most energies where the phonon
The superconducting transition temperatures and normal state residual electrical resistivities of the ternary Chevrel phase compounds CUl.8MosSs\_ySey (0 <~ y ~ 8) and Cul~MO6Se.y Tey (0 ~ y ~ 4) are reported. The data are examined for possible correlations with structural parameters of the rhombohe
