Halide-Driven Stabilization of a Hexagonal Polymorph with a Distinct and Disordered Li Substructure in Li3.25GeS3.25Cl0.75
Targeted halide substitution provides an effective route to access structural motifs in thio-LISICON systems. Here, partial substitution of S2– by Cl– in Li4GeS4 stabilizes a hexagonal polymorph near the composition Li3.25GeS3.25Cl0.75. Ab initio structure determination by joint refinement of time-of-flight neutron p...
