Reversible solvent-triggered single-crystal-to-single-crystal (SCSC) transformations are observed between two copper(II) azamacrocyclic complexes: [Cu(CHN)(HO)](CHO) (1) and [Cu(CHN)(CHO)] (2). Complex (1) was prepared via self-assembly of a copper(II) azamacrocyclic complex containing butyl pendant groups, [Cu(CHN)(ClO)], with 2,7-naphthalenedicarboxylic acid. When monomeric compound (1) was immersed in CHOH, coordination polymer (2) was obtained, indicating a solvent-triggered SCSC transformation. Furthermore, when (2) was immersed in water, an reverse SCSC transformation from (2) to (1) occurred. Complex (1) presents a 3D supramolecular structure formed via intermolecular hydrogen-bonding interactions, whereas complex (2) features a 1D zigzag coordination polymer. The reversible SCSC transformation of (1) and (2) was characterized using single-crystal X-ray diffraction and in situ powder X-ray diffraction techniques. Despite its poor porosity, complex (2) displayed interesting CO adsorption behaviour under CO gas.

Guest transport through discrete voids (closed pores) in crystalline solids is poorly understood. Herein, we report the gas sorption properties of a nonporous coordination network, [Co(bib)2Cl2]n·2MeOH (sql-bib-Co-Cl-α), featuring square lattice (sql) topology and the bent linker 1,3-bis(1H-imidazol-1-yl)benzene (bib). The as-synthesized sql-bib-Co-Cl-α has 11.

Stimulus-responsive molecular materials are highly desirable because of the wide range of their potential applications. In particular, switching of physical properties opens application pathways for molecular materials as sensors or actuators. Property switching in solids can be achieved by inducing single-crystal-to-single-crystal (SCSC) phase transitions.

The packing of organic molecular crystals is often dominated by weak non-covalent interactions, making their rearrangement under external stimuli challenging to understand. We investigate a pressure-induced single-crystal-to-single-crystal (SCSC) transformation between two polymorphs of 2,4,5-triiodo-1-imidazole using machine learning potentials. This process involves the rearrangement of halogen and hydrogen bonds combined with proton transfer within a complex solid-state system.

Article Synopsis
- Stimuli-responsive switchable molecules have great potential as magnetic materials for functional devices, but creating complexes with controlled switchability is challenging due to sensitivity to lattice interactions.
- The study presents a tailored [FeCo] square complex that incorporates hydrogen bonding interactions, leading to significant changes in magnetic properties through a single-crystal-to-single-crystal transformation.
- Notably, the complex exhibits multi-responsive properties with a unique thermal behavior, allowing for controlled switchability, and insights are provided for designing advanced materials for applications in actuators and sensors.
