Valverde-Munoz, Francisco Javier; Bartual-Murgui, Carlos; Pineiro-Lopez, Lucia; Munoz, M. Carmen; Real, Jose Antonio published their research in Inorganic Chemistry on August 5 ,2019. The article was titled 《Influence of Host-Guest and Host-Host Interactions on the Spin-Crossover 3D Hofmann-type Clathrates {FeII(pina)[MI(CN)2]2}·xMeOH (MI = Ag, Au)》.Name: N-(Pyridin-4-yl)isonicotinamide The article contains the following contents:
The synthesis, structural characterization and magnetic properties of two new isostructural porous 3-dimensional compounds {FeII(pina)[MI(CN)2]2}·xMeOH (x = 0-5; pina = N-(pyridin-4-yl)isonicotinamide; MI = AgI and x ∼ 5 (1·xMeOH); MI = AuI and x ∼ 5 (2·xMeOH)) are presented. The single-crystal x-ray diffraction analyses revealed that the structure of 1·xMeOH (or 2·xMeOH) presents two equivalent doubly interpenetrated 3-dimensional frameworks stabilized by both argentophilic (or aurophilic) interactions and interligand C=O···HC H-bonds. Despite the interpenetration of the networks, these compounds display accessible void volume capable of hosting up to five mols. of MeOH which interact with the host pina ligand and establish an infinite lattice of H bonds along the structural channels. The magnetic studies showed that solvated complexes 1·xMeOH and 2·xMeOH display two- and four-step hysteretic thermally driven spin transitions, resp. However, when these compounds lose the MeOH mols., the magnetic behavior changes drastically giving place to gradual spin conversions evidencing the relevant influence of the guest mols. on the spin-crossover properties. Importantly, since the solvent desorption takes place following a single-crystal-to-single-crystal transformation, empty structures 1 and 2 (x = 0) could be also determined allowing the authors to evaluate the correlation between the structural changes and the modification of the magnetic properties triggered by the loss of MeOH mols.
