Extending lead-free organic-inorganic semiconducting materials to new polymeric structures: 2,2'-bipyridinium iodoantimonate and quinoxalinium iodobismuthate.

ABSTRACT: We report on the synthesis, crystal structures and optoelectronic properties of two novel organic-inorganic group V iodometalates - (bpy-H)SbI₄ (1) and (Qx-H)₂[BiI₄]₂·CH₃OH (2) (bpy-H: 2,2'-bipyridinium; Qx-H: quinoxalinium). Crystals of both compounds were grown solvothermally using as starting reagents antimony(iii) iodide and 2,2'-bipyridine, for 1, and bismuth(iii) iodide and quinoxaline, for 2. Both compounds were structurally analyzed by single crystal X-ray diffraction at 100 K and their structures feature one-dimensional edge-sharing anionic chains of MI₆-octahedra, with short interchain I⋯I contacts giving rise to the possibility of three-dimensional charge transport capability. The cavities between the one-dimensio
