摘要：
The extinction conditions associated with the observed incommensurate satellite reflections of the low (i.e. <or approximately=1400 degrees C) specimen preparation temperature Yb3-deltaS4 phase are used to provide a crystallographic description of this modulated structure. The superspace group is found to be P11sPnma if the primary modulation wave-vector is chosen to fall inside the first Brillouin zone of the average structure.
