Here, we report lead halide crystals incorporating 2,2\u2032-bipyridinium (bpy), where the various valence states of bpy depending on its degree of protonation influence the structure of inorganic sublattices. We synthesized [bpy+]PbCl3 and [bpy2+]3Pb3Br10\u00b72Br, together with previously reported [bpy2+]2Pb3I10. [bpy2+]3Pb3Br10\u00b72Br and [bpy2+]2Pb3I10 incorporate trans-isomer divalent [bpy2+], consistent with synthetic conditions in strong acids, while [bpy+]PbCl3 exhibits a preference toward cis-isomer monovalent [bpy+]. They exhibit distinct Pb-X octahedral stacking patterns, i.e., chained or layered structures. Their bandgaps also depend on the halogen species and inorganic frameworks, while the intramolecular type II band alignment between the inorganic and organic sublattices contributes to the electronic structures in all cases, as suggested by theoretical calculations. This study emphasizes the importance of molecular structures in addition to halide components for crystal structure engineering in perovskitoids.<\/p>\n<p><a href=\"https:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acs.inorgchem.5c01798\"><br \/>\n<em>Inorg.
