In the title complex, {[Co(C6H8N2O2)(C9H7NO2)(H2O)2](ClO4)2}n, the CoII ion lies on an inversion center and is coordinated in a slightly distorted octahedral environment. The 2,5-dimethylpyrazine 1,4-dioxide ligand, which also lies on an inversion center, acts as a bridging ligand, linking symmetry-related CoII ions [Co…Co = 8.669 (3) Å] and forming one-dimensional chains along the b axis. In the crystal structure, these chains are linked by intermol. aqua-perchlorate O-H…O hydrogen bonds, forming two-dimensional layers which are in turn connected into a three-dimensional network via π-π stacking interactions between quinoline rings, with a centroid-centroid distance of 3.580 (3) Å.

Oshita, Hiromi; Suzuki, Takashi; Kawashima, Kyohei; Abe, Hitoshi; Tani, Fumito; Mori, Seiji; Yajima, Tatsuo; Shimazaki, Yuichi published the article 《π-π Stacking interaction in an oxidized CuII-Salen complex with a side-chain indole ring: An approach to the function of the tryptophan in the active site of galactose oxidase》. Keywords: galactose oxidase active site mimic copper salen complex tryptophan; copper; heterocycles; oxidation; pi interactions; radicals.They researched the compound: (S)-Propane-1,2-diamine dihydrochloride( cas:19777-66-3 ).Formula: C3H12Cl2N2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:19777-66-3) here.

In order to gain new insights into the effect of the π-π stacking interaction of the indole ring with the CuII-phenoxyl radical as seen in the active form of galactose oxidase, we have prepared a CuII complex of a methoxy-substituted salen-type ligand, containing a pendent indole ring on the dinitrogen chelate backbone, and characterized its one-electron-oxidized forms. The X-ray crystal structures of the oxidized CuII complex exhibited the π-π stacking interaction of the indole ring mainly with one of the two phenolate moieties. The phenolate moiety in close contact with the indole moiety showed the characteristic phenoxyl radical structural features, indicating that the indole ring favors the π-π stacking interaction with the phenoxyl radical. The UV/Vis/NIR spectra of the oxidized CuII complex with the pendent indole ring was significantly different from those of the complex without the side-chain indole ring, and the absorption and CD spectra exhibited a solvent dependence, which is in line with the phenoxyl radical-indole stacking interaction in solution The other physicochem. results and theor. calculations strongly support that the indole ring, as an electron donor, stabilizes the phenoxyl radical by the π-π stacking interaction.

Application of 217192-22-8. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: (4-(Pyridin-4-yl)phenyl)methanol, is researched, Molecular C12H11NO, CAS is 217192-22-8, about Rotaxanes Based on the 1,2-Bis(pyridinio)ethane-24-Crown-8 Templating Motif.

The supramol. interaction between 1,2-bis(pyridinio)ethane axles and 24-membered crown ether wheels provides a template for the formation of interpenetrated [2]pseudorotaxanes. The preformed [2]pseudorotaxanes can then be kinetically trapped to produce permanently interlocked [2]rotaxanes by stoppering with bulky groups that prevent the unthreading of the resulting dumbbell from the wheel. Six [2]rotaxanes were created using 24-crown-8 (24C8), dibenzo-24-crown-8 (DB24C8) and dinaphtho-24-crown-8 (DN24C8) as the wheel and two methods of stoppering; alkylation of a terminal pyridine with tert-butylbenzyl groups and esterification of a terminal benzyl alc. with p-(tert-butyl)benzoate groups. The [2]rotaxanes were characterized by 1H NMR spectroscopy, electro-spray mass spectrometry and X-ray crystallog.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (S)-Propane-1,2-diamine dihydrochloride, is researched, Molecular C3H12Cl2N2, CAS is 19777-66-3, about From Mesocates to Helicates: Structural, Magnetic and Chiro-Optical Studies on Nickel(II) Supramolecular Assemblies Derived from Tetradentate Schiff Bases.Electric Literature of C3H12Cl2N2.

The systematic reactions of a family of tetradentate pyridyl/imine and quinolyl/imine racemic or enantiopure Schiff bases with Ni(NO3)2 or Ni(ClO4)2 in the presence of sodium azide yielded, as a function of the starting racemic, chiral or achiral base, a set of chiral, meso or achiral complexes. In all cases, the compounds consist of two NiII cations linked by a double azido bridge in its end-on coordination mode. All the dimers exhibit a mesocate supramol. structure and one of them, the unprecedented mix of helicate and mesocate in 2:1 ratio. The transition from mesocate to helicate conformation was reached by tuning the flexibility of the central spacers of the Schiff bases and the size of the substituents. Electronic CD (ECD) studies were performed for two pairs of enantiomers and interpreted by DFT calculations Susceptibility measurements show a ferromagnetic coupling between the NiII cations mediated by the end-on azido bridges.
