A systematic study of the crystal structure of a layered iron oxypnictide LaFeAsO<sub>1-x</sub>H<sub>x</sub> as a function of pressure was performed using synchrotron X-ray diffraction. This compound exhibits a unique phase diagram of two superconducting phases and two parent phases. We established that the As-Fe-As angle of the FeAs<sub>4</sub> tetrahedron widens on the application of pressure due to the interspace between the layers being nearly infilled by the large La and As atoms. Such rare ...[more]
