The influence of dopant molecules on the structure and functionality spin-crossover (SCO) materials is surveyed. Two aspects topic are well established. Firstly, isomorphous inert metal ion dopants in SCO lattices a useful probe energetics processes. Secondly, molecular alloys iron(II)/triazole coordination polymers containing mixtures ligands were used to tune their spin-transitions towards room temperature. More recent examples these related discussed that reveal new insights into questions. Complexes which not can also be co-crystallised, either as solid solutions precursor or random distribution homo- hetero-leptic centres alloy. This could powerful method manipulate functionality. Published show different behaviours, may include allosteric switching chemically distinct sites.

The integration of polyoxometalate (POM) anions with functionalized cations within a single molecule remains challenging task, even though POMs have garnered significant interest over an extended period. Here, we constructed two cobalt(II) complexes by incorporating isomeric POM [Co(pyterpy)2]2+. Intriguingly, locked high-spin (HS) state and spin-crossover (SCO) behavior the 3d7-CoII ion in identical cation [Co(pyterpy)2]2+ were governed α-type β-type [Mo8O26]4- anions, HS-Co(II) showed field-induced slow magnetic relaxation. Furthermore, both exhibited potential as solid-state proton conductors. This study revealed that possessed dual capability modulating magnetism synthesizing multifunctional molecular materials.
