      abstract     = {A high-throughput compositional screening of
                      perovskite-like Cs3M2X9 double salts (M = Bi and Sb and X =
                      Cl, Br, and I) allows independent variation of the M and X
                      components, yielding one hundred single-phase products
                      within a general synthetic approach that combines engineered
                      precipitation of chloride and bromide precursors and their
                      anion exchange conversion into more complex halide
                      derivatives. The X variation at a fixed M = Bi3+ yields
                      various single-phase Cs3Bi2X9 compounds with X = Cl, Cl +
                      Br, Br, Br + I, and Cl + Br + I. The anion exchange in
                      chlorides with Br + I combinations produces stable Cs3Bi2X9
                      compounds with all three halides simultaneously present in
                      the lattice, and Cl, Br, and I contents varied in the ranges
                      of ca. $40–90\%,$ $10–60\%,$ and $30–90\%,$
                      respectively. The presence of bromide, even as a residue,
                      enables the co-existence of Cl and I, and dictates the
                      trigonal symmetry, in contrast to the hexagonal symmetry
                      typical for Cs3M2I9. The compounds with X = Cl + Br + I show
                      band gap variations in the range of 2.0–2.5 eV and linear
                      dependencies on the iodide content and lattice parameters.
                      The simultaneous variation of the X and M sites yields
                      single-phase Cs3(Bi,Sb)2X9 solid-solution compounds with
                      tailorable X and a Bi/Sb ratio varied from 0 to 1.0. All
                      Bi/Sb families reveal a band bowing effect, with the band
                      gaps of mixed Bi/Sb compounds being lower than those of Bi-
                      and Sb-only counterparts. The bowing parameter depends on
                      the X subsystem, decreasing from 0.80 eV for Cl to 0.60 eV
                      for Cl + Br and 0.40–0.45 eV for Br and Br + I, indicating
                      that chemical variations in the mixed Bi/Sb lattices, rather
                      than local disorders or lattice strains, govern the
                      band-bowing behavior.},
