The role of π-blocking hydride ligands in a pressure-induced insulator-to-metal phase transition in SrVO2H

Abstract

Incorporating hydride anions into transition metal oxides can dramatically affect their structural and electronic properties. Here the authors reveal a pressure-induced insulator-to-metal transition in SrVO2H and show that the compressibility of hydride anions without π-symmetry valence orbitals causes them to act as π-blockers.
