This work demonstrates how hydrogen bonds govern phase behavior and thermal responses in lead halide hybrids, suggesting design strategies for materials.

Key Points

To explore how hydrogen bonding affects the structure and thermal properties of lead halide hybrid materials.
Investigation of hydrogen bonds in MA(18-C-6)PbX3 compounds with X = Cl, Br, I.
Analysis of crystal structure and phase transitions based on hydrogen-bonding motifs.
Examination of thermal expansion properties along different geometric directions.
Hydrogen bonds effectively control the coordination geometry of PbXn polyhedra.
Observed distinct phase transition behaviors linked to the hydrogen-bonding interactions.
Materials showed negative and near-zero thermal expansion along the chain direction.
