The reconstructed 3D reciprocal lattice for Li-2-SAPO-RHO (Fig. ) revealed an I-centered cubic unit cell with dimensions of a = 14.50 Å. Two-dimensional slices of the cRED data exhibited reflection conditions of 0kl (k + l = 2n) and hhl (l = 2n) (Fig. and), indicating possible space 10 groups of I23, I213, and I432. Intensity data were extracted using the X-ray Detector Software (XDS) package , and structural modeling using direct methods in SHELXT confirmed I23 as the space group (table ).
