Single-crystal SAXS experiments with heterobinary AuEnc^(neg)/eFtn^(pos) (A), eEnc^(neg)/CeFtn^(pos) (B), and AuEnc^(neg)/CeFtn^(pos) (C) crystals. On the left, models of the unit cell with different NP loadings are shown, while on the right, the experimental data (black) are compared with the simulated data (colored). Simulated data for an AB₃ structure are indicated by a brighter color, while an AB₄ structure features a darker color. Reflections only present in structure type AB₃ are labeled with “AB₃ only”. (A) The observed reflections for the AuEnc^(neg)/eFtn^(pos) crystal fit to the simulated data (red) of a primitive cubic lattice where only the gold nanoparticle is present within the unit cell. (B) The observed diffraction for the eEnc^(neg)/CeFtn^(pos) crystal fits to an AB₃ structure with three cerium oxide nanoparticles in one unit cell but does not exclude the presence of unit cells of an AB₄ structure (blue). (C) For the AuEnc^(neg)/CeFtn^(pos) crystal, the observed reflections fit to the simulated data (green).
