Abstract:

The M -phase of fergusonite is closely related to the other known monoclinic form M-phase, except that it has a halved b-axis and its space group is P2a instead of I2. The structure of the M -phase was determined for YTaO4 from three-dimensional diffractometer data, and its relationship to the other polymorphs is discussed. The lattice parameters of M -YTaO are a 5.292A, b 5.451A, c 5.110A, beta 96.44 deg., Z 2. Author
