Bandgap modification in 0D tellurium iodide perovskite derivatives <i>via</i> incorporation of polyiodide species

Abstract
octahedron asymmetry as compared to previously published compounds, with greater asymmetry correlating with higher van der Waals overlap of halogen-halogen contacts. We also demonstrate the ability of hydrogen and carbon bonding (which dominates in the absence of polyiodides) to affect inner sphere tellurium iodide bonding and octahedral symmetry.
