The values of critical temperatures for alloys of Pb- and SnMo{sub 6}S{sub 8} were shown to be lower than those of the respective pure Chevrel phases. Chemical compositional analysis of the compounds revealed that the decreased {Tc} in the alloys are due to the off-stoichiometric compositions in the alloys. Although alloying slightly increased the values of the upper critical field H{sub c2} over that for PbMo{sub 6}S{sub 8}, the H{sub c2} values for these specimens were substantially lower than those which have been reported for PbMo{sub 6}S{sub 8}. Possible causes for these depressed values of H{sub c2} are discussed.
