Time-of-flight neutron powder diffraction (TOF-NPD) and synchrotron X-ray powder diffraction (SXPD) experiments were carried out to study the crystal structure of 7Li isotope enriched 7Li7P 3S11 glass ceramics, which is a lithium superionic conductor. Combined X-ray/neutron Rietveld refinement informed us precise atomic coordinates, especially lithium. Furthermore, a network of neighboring Li + cations was visualized in the crystal structure of Li 7P3S11 with the triclinic system (space group: P1̄) in order to predict the diffusion pathway of Li+ cations.
