Two superconducting phases of Re${}_{3}$W have been found with different physical properties. One phase crystallizes in a noncentrosymmetric cubic ($\ensuremath{\alpha}$-Mn) structure and has a superconducting transition temperature ${T}_{c}$ of 7.8 K. The other phase has a hexagonal centrosymmetric structure and is superconducting with a ${T}_{c}$ of 9.4 K. Switching between …
