abstract = {Li3Y1–xInxCl6 undergoes a phase transition from trigonal
to monoclinic via an intermediate orthorhombic phase.
Although the trigonal yttrium containing the end member
phase, Li3YCl6, synthesized by a mechanochemical route, is
known to exhibit stacking fault disorder, not much is known
about the monoclinic phases of the serial composition
Li3Y1–xInxCl6. This work aims to shed light on the
influence of the indium substitution on the phase evolution,
along with the evolution of stacking fault disorder using
X-ray and neutron powder diffraction together with
solid-state nuclear magnetic resonance spectroscopy,
studying the lithium-ion diffusion. Although Li3Y1–xInxCl6
with x ≤ 0.1 exhibits an ordered trigonal structure like
Li3YCl6, a large degree of stacking fault disorder is
observed in the monoclinic phases for the x ≥ 0.3
compositions. The stacking fault disorder materializes as a
crystallographic intergrowth of faultless domains with
staggered layers stacked in a uniform layer stacking, along
with faulted domains with randomized staggered layer
stacking. This work shows how structurally complex even the
“simple” series of solid solutions can be in this class
of halide-based lithium-ion conductors, as apparent from
difficulties in finding a consistent structural descriptor
for the ionic transport.},
