Orthorhombic MoTe₂ has been proposed to be a type II Weyl semimetal. This classification is supported by the observation of rare topological phenomena such as Fermi arcs and Weyl nodes through ARPES measurements. Superconductivity is also observed in this material, with a drastic pressure enhancement of the superconducting transition temperature often associated with a first-order structural transition from the non-centrosymmetric orthorhombic phase to a centrosymmetric monoclinic phase with uncertain band topology. I will discuss the temperature-pressure structural phase diagram of this system as determined by neutron scattering at conditions relevant for superconductivity. I will also comment on possible implications of the structural evolution on the ground state electronic structure.
