## Abstract We have examined the effect of composition on the Raman-active vibrational response of the Cu~2~(Fe~x~Zn~1−x~)SnS~4~ and Cu~2~(Mn~x~Zn~1−x~)SnS~4~ solid solution series at ambient conditions. Based on these results we were able to identify the phase boundaries of the respective kesterite-type and stannite-type structures adopted by these compounds as a function of composition. In the case of Cu~2~(Fe~x~Zn~1−x~)SnS~4~, our observations correlate very well with earlier reports. For the Cu~2~(Mn~x~Zn~1−x~)SnS~4~ series, on the other hand, we were able to clearly pinpoint the kesterite↔stannite transition for intermediate compositions for the first time, indicating that Raman spectroscopy can serve as an efficient method for monitoring subtle structural transitions in these systems.
