We performed the neutron powder diffraction and synchrotron X-ray diffraction measurements on CeFeAsO $_{1-x}$ (D,H) $_{x}$ ( = 0.0-0.48) as a representative of 1111-type family of iron-based superconductors LnFeAsO $_{1-x}$ H $_{x}$ ( = lanthanoid). These results strongly suggest that H $^{-}$ ions exclusively occupy the oxygen sites in both samples, regardless of the hydrogen species in the starting material.
