The reactions of two kinds of substituted 1,2,4-triazoles with BiI{sub 3} yielded three inorganic-organic hybrids: [HL1]{sub 4}[Bi{sub 6}I{sub 22}].[L1]{sub 4}.4H{sub 2}O (1) (L1=3-(1,2,4-triazole-4-yl)-1H-1,2,4-triazole); [HL2]{sub 4}[Bi{sub 6}I{sub 22}].6H{sub 2}O (2); [HL2]{sub 2}[Bi{sub 2}I{sub 8}].[L2]{sub 2} (3) (L2=(m-phenol)-1,2,4-triazole). Both 1 and 2 have polynuclear anions of [Bi{sub 6}I{sub 22}]{sup 4-} to build up the inorganic layers and substituted 1,2,4-triazoles as the organic layers. Hybrid 3 consists of two BiI{sub 5} square pyramids as inorganic layers. There exist hydrogen bondings and I...;I interactions in the structures of 1, 2 and 3. Optical absorption spectra of 1, 2 and 3 reveal the presence of sharp optical gaps of 1.77, 1.77 and 2.07 eV, respectively, suggesting that these materials behave as semiconductors. - Graphical abstract: The reactions of two kinds of the substituted 1,2,4-triazoles with BiI{sub 3} yielded three layered inorganic-organic hybrids [HL1]{sub 4}[Bi{sub 6}I{sub 22}].[L1]{sub 4}.4H{sub 2}O (1), [HL2]{sub 4}[Bi{sub 6}I{sub 22}].6H{sub 2}O (2), [HL2]{sub 2}[Bi{sub 2}I{sub 8}].[L2]{sub 2} (3) with optical gaps of 1.77, 1.77 and 2.07 eV, respectively. The structures of 1-3 are constructed from inorganic layers of polynuclear anions of bismuth iodine and organic layers of the substituted 1,2,4-triazoles.
