The cationic Fe(NO)N2S2⋅Fe(NO)2+ complex, 1+, of Enemark–Feltham electronic notation {Fe(NO)}7‐{Fe(NO)2}9, is readily obtained via myriad synthetic routes, and shown to be spin coupled and diamagnetic. Its singly and doubly reduced forms, {Fe(NO)}7‐{Fe(NO)2}10, 10, and {Fe(NO)}8‐{Fe(NO)2}10, 1−, were isolat

WolynesJournal of the American Chemical Society 138 (41), pp 13497–13500Fis protein is a nucleoid-associated protein that plays many roles in transcriptional regulation and DNA site-specific recombination. In contrast to the naïve expectation based on stoichiometry, recent single-molecule studies have shown that the dissociation of Fis protein from DNA is accelerated by increasing the concentration of the Fis protein. Because the detailed molecular mechanism of facilitated dissociation is still not clear, in this study, we employ computational methods to explore the binding landscapes of Fis:DNA complexes with various stoichiometries. When two Fis molecules are present, simulations uncover a ternary complex, where the originally bound Fis protein is partially dissociated from DNA. The simulation

In this work, for the first time, we have successfully generated coordinatively unsaturated metal sites (CUMSs) in phytic acid–Co2+ (Phy–Co2+) based metal–organic complexes by engineering the coordination geometry with room-temperature plasma technology. The CUMSs can serve as active centers to catalyze the OER. The electron spin resonance and X-ray absorption spectra provide direct evidence that the coordination geometry is obvio

Combinations of NiN2S2 or [(NO)Fe]N2S2 as donors to (η5-C5H5)Fe(CO)+ or [Fe(NO)2]+/0 generate a series of four bimetallics, gradually “softened” by increasing nitrosylation, from 0 to 3, by the non-innocent NO ligands. The nitrosylated NiFe complexes are isolated and structurally characterized in two redox levels, demonstrating required features of electrocatalysis.

The organisms use them to maintain their life. Herein, we introduce a special enzyme: Cysteine Dioxygenase (CDO); CDO is a non-heme iron enzyme, which can convert cysteine (Cys) into cysteine sulfinic acid (CSA). This conversion plays an important role in cysteine catabolism in mammalian tissue. Deficiency of CDO has been correlated with Alzheimer’s, Parkinson’s and other neurological disorders. Structural comparison from the typical non-hemeFe(II) dioxygenases to CDO, the coordination sphere of the Fe in CDO deviates fromthe fac-2-Histeines-1-carboxylate to a 3-Histein

We investigate the adsorption properties of these complexes between gaseous molecules and HDG-M. Our results show that HDG-Cu has a high selectivity for O2, but HDG-Fe has a good ability to capture many gases such as CO, NO and O2.

S. Su; S. J. Hsu; Jing C. W. Tseng; Hsiu-Fu Hsu; Wen-Jwu Wang; Ivan J. B. LinChemistry 22(1), pp.323-330Examples of polynuclear metallomesogens are few. Herein,1,2,4-triazole ligands were used to prepare mono- and polynuclear silver(I) triazole metallomesogens. Besides showing an SmA phase in the mesophase, two interesting properties were observed. First, higher ion conductivity is always found for the polynuclear complexes than for the mononuclear complexes with the same anion, an observation contrary to the knowledge that migration of a monomeric cation should be faster than that of a polymeric cation. Second, thermolysis of the polynuclear silver(I) triazole complexes in the assembled mesophase yielded Ag nanowires, in an excellent demonstration of the assembled nature of the polynu

When the system was immersed in the solution containing Hg2+, the complex of ZT and Hg2+ formed, which disrupted the orientation of LC and lead to a dark-to-bright transition of the image of LCs.

With M = Fe, a diamagnetic (N2S2)Fe(NO)·Fe(NO)2 diiron complex, in which the (N2S2)Fe(NO) unit serves as a bidentate ligand to the Fe(NO)2 unit is derived by use of a trinitrosyliron cation as precursor to the DNIC unit as well as a NO source to cleave the [(bme-dach)Fe]2 dimer (J.

Reaction of Lligand strands with nickel(II) perchlorate in CH3 CN generates a double helical dinuclear complex. Its complexation behavior was studied by UV-Vis spectrophotometric titration experiments that revealed the formation of dinuclear complexes [Ni2L2](ClO4)4. Moreover, the double-helical structure of [Ni2L2](ClO4)4 was confirmed by X-ray diffractometer. Each nickel(II) center occupies a distorted octahedral environment. Variable

An integral ruthenium complex exists inside the cell as identified by matrix-assisted laser desorption ionization (MALDI) mass spectrometry. An inhibition assay with Escherichia coli was used to demonstrate the relationship between the transportation of the polypyridyl ruthenium complexes and the presence of OmpF (outer membrane protein F).
