| Abstract: | Reactions of Sb2O3 or Bi2O3, 1,2-bis(4-pyridyl)ethane (bpe) and diiodine in concentrated HI resulted in isostructural salts (H2bpe)2[MI6](I3) [M = Sb (1), Bi (2)] featuring perovskite-like arrangement of anions in crystal packing. Physical properties, including UV-Vis and Raman spectra, as well as thermal stability, were investigated and compared for this pair of complexes; the optical band gaps for 1 and 2 are 1.32 and 1.57 eV, respectively. |
