The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1H-Pyrazole-5-carbaldehyde, is researched, Molecular C4H4N2O, CAS is 948552-36-1, about Ferromagnetic Superexchange Coupling through a Diamagnetic Iron(II) Ion in a Mixed-Valent Iron(III, II, III) meso-Helicate, the main research direction is iron nickel pyrazolylnitrone trinuclear complex structure magnetism; ferromagetic superexchange mixed valent iron pyrazolylnitrone trinuclear complex; crystal structure iron nickel pyrazolylnitrone trinuclear complex.Quality Control of 1H-Pyrazole-5-carbaldehyde.
Meso-Helicates [Ni3(pzNTR)6]·4CH3CN and [Fe3(pzNTR)6](ClO4)2·CH3OH were prepared (HpzNTR = N-tert-butyl-α-3-pyrazolylnitrone). The former showed antiferromagnetic coupling between neighboring ions with J/kB = -28.2(2) K, which can be reasonably interpreted in terms of the superexchange mechanism. However, the latter exhibited ferromagnetic coupling with J/kB = +0.292(8) K between the two terminal S = 5/2 Fe3+ ions through the intervening diamagnetic Fe2+ ion. The admixture of low-lying excited states with the ground state stabilizes the ferromagnetically coupled state, like the Prussian blue magnet.
There is still a lot of research devoted to this compound(SMILES：O=CC1=CC=NN1)Quality Control of 1H-Pyrazole-5-carbaldehyde, and with the development of science, more effects of this compound(948552-36-1) can be discovered.
