`The octahedral manganese(III) complex, [Mn$^\mathrm{III}$(taa)] (H$_3$taa = tris(1-(2-azolyl)-2-azabuten-4-yl)amine), has long been known as a rare example of (3d)$^4$ spin-crossover system, having a steep spin-crossover phase transition at $T_\mathrm{c}$ = 48 K between a high-spin $^5$E$_g$ and a low-spin $^3$T$_{2g}$ states [1, 2]. Since the high-spin state is obviously subject to the...

`Cyanido-bridged clusters serve as convenient coordination platforms for switchable materials, to mention single-molecular magnets (SMMs) or spin-crossover (SCO) systems and charge-transfer induced spin transitions (CTIST) systems combined with light induced excited spin state trapping (LIESST). Their functional potential can be strengthened by decoration of external complexes using chiral or...

`Mononuclear lanthanide complexes, that behave as Single-Ion Magnets (SIMs) have only been studied in the last 15 years (the interest was triggered by the work of Ishikawa on terbium phtalocyaninate in 2003). In these complexes, in which the Ln(III) ion is surrounded by organic ligands in a low symmetry environment, the crystal-field splitting of the J ground state of the lanthanide ion gives...

`[Co(NCS)$_2$py$_2$]$_n$ (py – pyridine) is composed of irregular ferromagnetic chains of Co(II) ions linked by the double NCS bridges. The coordination polyhedron of the Co(II) ion is a distorted octahedron built from equatorial two N and two S and two apical N atoms of the pyridine ligands. There are two inequivalent Co(II) ions which are magnetically coupled along chains in the $J_1 J_1...

`The possibility of inducing structural and magnetic changes by sorption of guest molecules is one of the important aspects of molecular magnetic materials that make them different from classical magnets based on metal alloys or oxides. This so called solvatomagnetic effect may find potential application in the design of molecular switches or sensors. It also provides valuable insight into the...
