Observation of spin-crossover behaviour in Co(ii)-terpyridine complexes possessing π-conjugated substations.

ABSTRACT: Exploring new compounds that exhibit spin-state switching under external stimuli is crucial for advancing materials science. However, the feasibility of combining π-conjugated moieties with Co(ii)-terpy cation units via an ethynyl group has not yet been investigated. This approach represents a hybridization strategy wherein distinct functional moieties are incorporated into a single coordination metal complex to achieve multifunctionality. In this study, we synthesised a series of Co(ii)-terpyridine complexes [Co(R-ethynyl-terpy)₂](BF₄)₂ (R = phenyl for 1, naphthyl for 2, anthracenyl for 3, and pyrenyl for 4), resolved their crystal structures and packing arrangements, and evaluated their magnetic properties using a superconducting quantum interferen
