Using high pressure synthesis under high hydrogen partial pressure condition, we synthesized a new analogue of iron-based superconductors LaFePH with a formal iron charge of 1+ and new oxyhydrides LaFePO1−xHxwithxranging 0 < x< 1. In contrast to the analogous arsenides LaFeAsO1−xHxand isoelectronic Co-oxyphosphide LaCoPO, neither superconducting, magnetic nor structural transitions were observed in LaFePO1−xHxexcept the already known superconducting transition inx= 0. DFT calculations reveal that the hydride ion substitution for the oxygen site dopes electrons into the Fe-3d and raises the Fermi level, leading to a partial electron transfer from the Fe-3d to La-5d. We attribute the absence of magnetism in LaFePH to the reduced onsite Coulomb interaction in the Fe-3d orbitals due to the expansion of the 3d orbital and the shielding effect of La-5d electrons.
