Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 13940-83-5, is researched, Molecular F2H8NiO4, about Influence of HF2- geometry on magnetic interactions elucidated from polymorphs of the metal-organic framework [Ni(HF2)(pyz)2]PF6 (pyz = pyrazine), the main research direction is nickel pyrazine bifluoride coordination polymer preparation heat capacity; magnetic exchange entropy nickel pyrazine bifluoride coordination polymer; optimized mol structure nickel pyrazine bifluoride coordination polymer; crystal structure nickel pyrazine bifluoride metal organic framework.Name: Nickel(ii)fluoridetetrahydrate.
A tetragonal polymorph of [Ni(HF2)(pyz)2]PF6 (designated β) is isomorphic to its SbF6-congener at 295 K and features linear Ni-FHF-Ni pillars. Enhancements in the spin exchange (JFHF = 7.7 K), Neel temperature (TN = 7 K), and critical field (Bc = 24 T) were found relative to monoclinic α-PF6. DFT reveals that the HF2- bridges are significantly better mediators of magnetic exchange than pyz (Jpyz), where JFHF ≈ 3Jpyz, thus leading to quasi-1D behavior. Spin d. resides on all atoms of the HF2- bridge whereas N-donor atoms of the pyz ring bear most of the d.
From this literature《Influence of HF2- geometry on magnetic interactions elucidated from polymorphs of the metal-organic framework [Ni(HF2)(pyz)2]PF6 (pyz = pyrazine)》,we know some information about this compound(13940-83-5)Name: Nickel(ii)fluoridetetrahydrate, but this is not all information, there are many literatures related to this compound(13940-83-5).
