Abstract We show that the conductivity of hybrid vanadium bronzes—mixed‐valence organic–inorganic oxides—can be tuned over six orders magnitude through judicious choice molecular component. By systematically varying steric profile, charge density, and propensity to hydrogen bond across a series eight diammonium‐based molecules, we engender multiple distinct motifs V−O connectivity within two‐dimensional oxide layers family bulk crystalline materials. A combination single‐crystal powder X‐ray diffraction analysis, variable‐temperature electrical transport measurements, range spectroscopic methods, including UV/Visible diffuse reflectance, photoelectron, electron paramagnetic resonance are employed probe how layer topology correlates with localization. Specifically, alkylammonium molecules yield hybrids featuring more corrugated contain tetrahedra as well higher ratio corner‐sharing edge‐sharing polyhedra exhibit highly localized electronic behavior, while alkyl bipyridinium regular polyhedral substantially delocalized behavior. This work allows for development design principles based on structure–property relationships brings capabilities bronzes technologically relevant levels.

We show that substitutional alloying during the aqueous self-assembly of layered organic-templated metal oxides produces single-phase mixed-metal hybrids. Single-crystal X-ray diffraction, bulk elemental analyses, and vibrational electronic spectroscopies corroborate a solid solution Mo W atoms at lattice sites within two-dimensional oxide layers. Mild postsynthetic reduction then introduces relatively delocalized electrons to afford hybrid bronzes. To our knowledge, this represents first demonstration in rare example solid-solution formation low temperature. approach yields congeners with optical band gaps over 130 meV smaller than those single-metal analogs, while achieving activation energies (Ea) conduction as 78.4(2) meV. Further, substitution appears tune collective phenomena by suppressing non-Arrhenius behavior observed for Mo-based This work considerably expands nascent bronze platform help address energy-related challenges fundamental solid-state physical questions.
