Recommanded Product: 767-00-0, In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 767-00-0, Name is 4-Hydroxybenzonitrile, SMILES is OC1=CC=C(C=C1)C#N, belongs to phthalazine compound. In a article, author is Hiiuk, Volodymyr M., introduce new discover of the category.
Two new 2D spin-crossover (SCO) analogues of Hofmann clathrates of composition [Fe(phth)(2)M-II(CN)(4)] (where phth = phthalazine; M-II = Pd, Pt) have been synthesized and their structures and switchable behaviour have been characterized. Single-crystal X-ray analysis reveals that the Pt and Pd derivatives contain Fe-II centres equatorially surrounded by four equivalent mu(4)-[M-II(CN)(4)](2-) groups. Two crystallographically equivalent phthalazine (phth) ligands occupy the axial positions of each Fe-II site, completing its octahedral coordination environment. The stabilization of these structures is realized via supramolecular C-HM interactions and pi-pi stacking. Temperature-dependent magnetic susceptibility measurements showed that Pt (T-1/2 down arrow = 211 K and T-1/2 up arrow = 218 K) and Pd (T-1/2 down arrow = 202 K and T-1/2 up arrow = 207 K) derivatives display cooperative spin crossover with narrow thermal hysteresis loops. In addition, spin crossover in these complexes was characterized by optical measurements, differential scanning calorimetry, and IR and Raman spectroscopy. This research shows that the use of phthalazine leads to the production of new SCO systems with attractive transition characteristics and opens up new perspectives for the design of switchable complexes based on fused bicyclic azine ligands.
