Abstract: Nanocrystallite δ′-ZrW1.6Mo0.4O8 was prepared in the precursor route synthesis. The characterization by means of powder X-ray diffraction (XRD) and selected area electron diffraction (SAED) showed it crystallized in a orthorhombic crystal system with a=0.896 9(7) nm, b=0.701 1(8) nm, c=0.596(1) nm. The possible space group is Pnnm (58) or Pnn2 (34). The compound crystallizes in a metastable phase during the synthesis process depending on temperature and crystallization time.
