Binuclear Metal Complexes with Novel Hexadentate Imidazole Derivative for the Cleavage of Phosphate Diesters and Biomolecules: Distinguishable Mechanisms

Phosphate bond cleavage is essential to physiological activity, antibacterial or antitumor as well the elimination of chemical warfare agents. In this work, three transition metal binuclear complexes (Cu2LCl4, Co2LCl4, Zn2LCl4)...

P2S2-Bridged binuclear metal carbonyls from dimerization of coordinated thiophosphoryl groups: a theoretical study

Theoretical studies indicate the complexes M(CO)n(PS) with bent 1-e/2-e donor PS groups to be unstable for giving the stable M(CO)n−1(PS) with linear 3-e donor PS groups. In addition, only Mn2(CO)8(P2S2) is energetically viable from the Mn(CO)4(PS).

Binuclear metal complexes of a symmetric polydentate donor hydrazone: synthesis, spectral characterization, DNP DFT computational and biological studies

Co(II), Ni(II)and Cu(II) complexes of a new chelate namely 2,2'-((9S,10S,11R,12R)-9,10-dihydro-9,10-ethanoanthracene-11,12-dicarbonyl)bis(N-phenylhydrazine-1-carboxamide) (H6EPH) were synthesized and were characterized by using analytical and spectral techniques suggesting tetrahedral geometry for Ni(II) and Cu(II) complexes and an octahedral for Co(II) complex. The ESR spectral data showed one broad band with g|| > 2.0036 indicating the axial symmetry with the unpaired electron residing in the dx2-y2 orbital with appreciable covalent character of the metal-ligand bond. The molecular modeling a using DFT method was drawn and the bond lengths, bond angles, chemical reactivity and energy components (kcal/mol) for all the title compounds were evaluated. Also, all compounds were examined for DNA cleavage ability and antioxidant using superoxide dismutase like- activity.

Excited state vibrational coherence in a binuclear metal adduct: wave packet phase dependant molecular fragmentation under variation of ligand size

Ultrafast vibrational coherence with metal-metal stretching mode character is observed for phosphine-bridged d10-d10 complexes of different size, containing the binuclear [Ag2Cl]+ chromophore in an ion trap. Fragmentation pathways are governed by the wave packet's phase.

Microstructure and electrochemical performance of LiFePO4 cathode materials modified with binuclear metal aminophthalocyanines

The monodispersed LiFe[Formula: see text]M[Formula: see text]PO4/C [[Formula: see text] [Formula: see text] 0.0040; [Formula: see text] = Mn[Formula: see text], Co[Formula: see text], Ni[Formula: see text], Cu[Formula: see text], Zn[Formula: see text]] nanocomposites obtained by LiFePO4 modified with binuclear metal aminophthalocyanines (M2(PcTa)2O and M2(PcTa)2C(CF[Formula: see text] are utilized as positive electrode materials for lithium ion batteries. The preparation method for these nanocomposites is a controllable solvothermal method using a mixture of ethylene glycol and [Formula: see text],[Formula: see text]-dimethylformamide as the solvent. The microstructure and electrochemical properties of the different nanocomposites are discussed and compared. The results show that the LiFePO4 samples modified with M2(PcTa)2C(CF[Formula: see text]can improve the initial discharge specific capacity of the lithium ion battery up to 154.2 mAh.g[Formula: see text]at the rate of 0.1 C, and 93.5% of the initial discharge capacity could be retained after 50 cycles. This research shows that the proposed process can enhance the electrochemical performance of high power LiFePO4 for lithium ion batteries.
