## Description

- description: Crystal−liquid−glass phase transitions in coordination polymers (CPs)
    and metal–organic frameworks (MOFs) have opened new opportunities for materials
    processing and for accessing novel or enhanced functionalities inherited from
    their crystalline precursors. However, strategies to modulate the properties of
    the resulting glassy states, collectively referred to as metal–organic glasses
    (MOGs), have primarily relied on crystal engineering. Such approaches face intrinsic
    limitations, as the rare occurrence of melting behavior in CPs/MOFs and the narrow
    compositional windows that sustain a stable liquid phase restrict access to new
    structures and properties. Inspired by the compositional tunability of conventional
    oxide glass, this work explores a strategy to modulate MOG properties by incorporating
    inorganic zirconium hydrogen phosphate as a secondary network former. We hypothesize
    that the mismatch between tetrahedrally coordinated Zn2+ in the parent MOG and
    octahedrally coordinated Zr4+ in the additive induces distinct structural and
    functional modifications. By systematically varying the content of the zirconium
    hydrogen phosphate, we demonstrate a linear increase in the glass transition temperature,
    viscosity, and anhydrous proton conductivity, reaching 2.6 mS cm−1 at 150 °C.
    These results highlight the potential of translating design principles from inorganic
    glass science to fine-tune the properties of MOGs.
