Here, the hyper-kagome lattice iridate Na₃Ir₃O₈, closely related to spin liquid candidate Na₄Ir₃O₈, is unusual in that spin-orbit interactions acting on the 1/3-filled J_eff = 1/2 state lead to a semimetallic ground state, in contrast to the conventional insulating Mott state stabilized by S-O interactions in the 1/2-filled J_eff = 1/2 state of other iridates including Na₄Ir₃O₈. We have studied the evolution of crystal structure, electronic structure, and transport in Na₃Ir₃O₈ under high pressure using x-ray diffraction, x-ray absorption near edge structure, and electrical resistance measurements in a diamond anvil cell. The study was augmented by the use of ab initio calculations, which provided insight into pressure-induced changes in crystal and electronic structure. We found that Na₃Ir₃O₈ transforms from a semimetal to an insulator under pressure, with an estimated energy gap that increases to about 130 meV at P similar to 9 GPa. At approximately 10 GPa, a cubic-to-monoclinic structural transition takes place between two insulating phases. This structural transition features a sizable volume collapse and a high-pressure phase characterized by apparent dimerization of Ir-Ir distances, wide dispersion of Ir-O-Ir bond angles, and an increase in the occupation of 5d states. Although the energy gap is reduced in the high-pressure phase, insulating behavior remains to the highest pressures similar to 1 Mbar. The strongly pressure-dependent insulating gap shows a positive correlation with the expectation value of the angular part of the S-O interaction, < L • S >, which may indicate an active role of S-O interactions in stabilizing the insulating state that emerges in the compressed Na₃Ir₃O₈ structure.
