Structural Changes during the Growth of Atomically Precise Metal Oxido Nanoclusters from Combined Pair Distribution Function and Small-Angle X-ray Scattering Analysis.

ABSTRACT: The combination of in situ pair distribution function (PDF) analysis and small-angle X-ray scattering (SAXS) enables analysis of the formation mechanism of metal oxido nanoclusters and cluster-solvent interactions as they take place. Herein, we demonstrate the method for the formation of clusters with a [Bi₃₈ O₄₅ ] core. Upon dissolution of crystalline [Bi₆ O₅ (OH)₃ (NO₃ )₅ ]⋅3 H₂ O in DMSO, an intermediate rapidly forms, which slowly grows to stable [Bi₃₈ O₄₅ ] clusters. To identify the intermediate, we developed an automated modeling method, where smaller [Bi_x O_y ] structures based on the [Bi₃₈ O₄₅ ] framework are tested against the dat
