The superconducting transition temperatures and normal state residual electrical resistivities of the ternary Chevrel phase compounds Cu1.8Mo6S8-YSey (0 ≤y ≤ 8) and Cu1.8Mo6S8-y Tey (0 ≤ y ≤4) are reported. The data are examined for possible correlations with structural parameters of the rhombohedral unit call and the residual resistivity values. It is found that Tc decreases as the c/a ratio increases and as the rhombohedral angle approaches 90°. There is also an inverse correlation between Tc and the normal residual resistivity of the samples. © 1982.
