Simultaneous presence of mono- and bi-cationic bipyridyls within a metal-organic supramolecular host: crystal structure, spectral and Hirshfeld surface analysis

Metal–cyanide hybrid materials exhibiting photochromic and photomagnetic responses based on viologen receptors

“…The [M III (CN) 6 ] 3− (M = transition metal) anion has garnered significant interest in functional D–A materials due to its dual role as a hydrogen bond acceptor and a donor of multiple electron pairs. 16–18 Built on earlier findings, integrating [M III (CN) 6 ] 3− into a D–A system has been shown to expand and finely tune the material's properties. 19–21 These anionic metal complexes have also been utilized in creating bimetallic compounds, incorporating lanthanide (Ln) elements as the secondary metal component.…”
