19F and 1H NMR investigations have been carried out on three powder samples of CsCaF3-xHx composition (0 ≤ x ≤ 1.70), and on a single crystal of CsCaF3. It appears that the spectra of 19F are consistent with a distortion of the Ca(F,H)6 octahedra involving either lower symmetry or a random distribution of a c4-maxis with respect to the crystallographic directions.
