WO3, an interlayer compound prepared by J. W. Johnson (1981) using yellow tungstic oxide hydrate. Suspension of white powdery tungstic acid in anhydrous pyridine yields on standing for 2 wk whiteHW4O13.3H2O. IR and DTA studies revealed the connection between that pyridine polytungstate and white powdery tungstic acid (microcryst.), whose composition may thereby be assigned as H2W4O13.nH2O.
