摘要:
Topotactic dehydration of either the white molybdenum trioxide monohydrate, MoO3 . H2O, or the hemihydrate, MoO3 . 1/2H(2)O, provides a convenient synthetic route to a high-pressure phase of molybdenum trioxide, MoO3-II. The structural filiations between the various molybdenum trioxide and trioxide hydrate phases are delineated, and simple mechanistic models for the transformations are proposed.
