Superstructures, due to cation vacancy ordering, form in the NiAs-related pseudobinary solid solution Fe7Se8-Fe7S8 close to both end compositions (Fe-7(SxSe1-x)(8) with x less than or equal to 0.15 and x greater than or equal to 0.85) during rapid cooling of quartz ampoules from 600 degrees C, according to X-ray diffractometry (XRD) and magnetization (SQUID) measurements. Mossbauer spectroscopy indicates local vacancy ordering in the whole interval, but XRD and SQUID data exclude long-range vacancy ordering when the anion proportion of sulphur is between 15% and 85%.
