Meneses-Sanchez, Manuel; Turo-Cortes, Ruben; Bartual-Murgui, Carlos; da Silva, Ivan; Munoz, M. Carmen; Real, Jose Antonio published the artcile< Enhanced Interplay between Host-Guest and Spin-Crossover Properties through the Introduction of an N Heteroatom in 2D Hofmann Clathrates>, Formula: C10H8N2, the main research area is transition metal Hofmann clathrate preparation host guest spin crossover; crystal structure iron bipyridine palladium platinum cyano Hofmann clathrate.
Controlled modulation of the spin-crossover (SCO) behavior through the sorption-desorption of invited mols. is an extensively exploited topic because of its potential applications in mol. sensing. For this purpose, understanding the mechanisms by which the spin-switching properties are altered by guest mols. is of paramount importance. Here, the authors show an exptl. approach revealing a direct probe of how the interplay between SCO and host-guest chem. is noticeably activated by chem. tuning the host structure. Thus, the axial ligand 4-phenylpyridine (4-PhPy) in the 2-dimensional Hofmann clathrates {Fe(4-PhPy)2[M(CN)4]} (PhPyM; M = Pt, Pd) is replaced by 2,4-bipyridine (2,4-Bipy), resulting in the isomorphous compounds {Fe(2,4-Bipy)2[M(CN)4]} (BipyM; M = Pt, Pd), which basically differ from the former in that they have a noncoordinated N heteroatom in the ancillary aromatic substituent, i.e., 2-pyridyl instead of Ph. Chem., magnetic, calorimetric, and structural characterizations demonstrate that this subtle chem. composition change provokes outstanding modifications not only in the capability to adsorb small guests as H2O or MeOH but also in the extent to which these guests affect the SCO characteristics.
