Embedded Cluster Study of the Co-Adsorption of HCl and H2O on PuO2 Surfaces

The simultaneous adsorption of HCl and H2O on the {111} and {110} surfaces of PuO2 has been studied using hybrid density functional theory within the periodic electrostatic embedded cluster method. A synergistic effect between co-adsorbed molecules is identified, such that HCl binding energies are enhanced by the presence of water. Higher levels of water also increase the HCl binding energy, forming very stable configurations on both surfaces for first-layer HCl interactions. Second-layer interactions are also explored, in which the HCl molecule is placed above a full monolayer of water on the surfaces. In such circumstances, the HCl reacts with a hydroxyl from the water monolayer to produce molecular water, with the chloride held to the surface via numerous chlorine-acceptor hydrogen bonds.

Monomeric zinc ferrocene carboxylate [Zn(FcCOO)(3,5-dmp)(2)Cl] derived from 3,5-dimethylpyrazole: structural, optical, electrochemical and antimicrobial studies

Monomeric zinc ferrocene carboxylate [Zn(FcCOO)(3,5-dmp)(2)Cl] (1) has been synthesized from a reaction between the zinc chloride, sodium salt of ferrocene carboxylic acid (FcCOONa) and 3,5-dimethylpyrazole (3,5-dmp) at room temperature. Compound 1 was further characterized by elemental analysis, H-1 NMR, FT-IR, absorption, emission spectroscopic techniques, and molecular structure was confirmed by single-crystal X-ray diffraction studies. The molecular structure of compound 1 crystallized in triclinic system with P (1) over bar space group and the central Zn2+ ion is in a distorted tetrahedral geometry with -FeN2OCl coordination environment. Compound 1 was further stabilized with the aid of inter and intramolecular hydrogen bonding and pi-pi interaction between cyclopentadienyl ring of ferrocene and aromatic heterocyclic five membered 3,5-dimethylpyrazole. Compound 1 exhibits broad emission band, indicating ligandto-metal charger transfer (LMCT) or metal-to-ligand charger transfer (MLCT) nature. The electrochemical property of compound 1 revealed that one-electron anodic and cathodic peaks corresponding to the redox responsible of ferrocene/ferrocenium (FeII <-> Fe-III) moiety. Among the different strains of bacteria, the antibacterial activity of compound 1 showed comparatively a significant activity against gram negative bacterium Proteus vulgaris. (C) 2020 Elsevier B.V.
