Unusual Dimeric Zn(II)-cytosine complexes: New models of the interaction of Zn(II) with DNA and RNA

Journal of Inorganic Biochemistry, 2008
Synthesis and crystal structure of two Zn(II) dimer complexes with 1-methylcytosine (1-MeC) are reported. In complex [Zn(2)Cl(4)(mu-1-MeC-O2,N3)(2)] (1), two 1-MeC ligands are bridging two ZnCl(2) moieties. In [Zn(2)(1-MeC-N3)(4)(mu-SO(4))(2)].2H(2)O (2), the sulfates act as bridging ligands and 1-MeC are linked via N3 to Zn(II) as terminal ligands ...

Lifetimes for Low-lying Levels in Zn I and Zn II

Physica Scripta, 1979
Lifetime measurements using the beam-foil technique have been made for levels in Zn I and Zn II. The following results (in ns) were obtained: ZnI, 4s4p 1P (1.33 ± 0.07), 4s4d 1D (20.5 ± 1.5), 4s4d 3D (5.4 ± 0.6); Zn II, 4p 2P (2.07 ± 0.20), 4d 2D (1.40 ± 0.15), 5s 2S (1.8 ± 0.2), 5p 2P (17 ± 2). These results are compared with previous experimental and

Modulation of Nuclearity by Zn(II) and Cd(II) in Their Complexes with a Polytopic Mannich Base Ligand:  A Turn-On Luminescence Sensor for Zn(II) and Detection of Nitroaromatic Explosives by Zn(II) Complexes

Crystal Growth & Design, 2018
Reactions of Zn(II) ion with the ligand H2L (H2L = N,N′-dimethyl-N,N′-bis(2-hydroxy-3-methoxy-5-methylbenzyl)ethylenediamine) in the presence of bridging coligands, chloride, thiocyanate/acetate, or azide/acetate yielded three new dinuclear complexes, [Zn2LCl2(H2O)] (1), [Zn2L(SCN)2(H2O)]·H2O (2), and [Zn2L(N3)(CH3CO2)] (3), whereas Cd(II) ion formed ...

Electrodeposition of Ni‐Zn Alloy: II . Electrocrystallization of Zn, Ni, and Ni‐Zn alloy

Journal of The Electrochemical Society, 1993
The initial stages of the electrodeposition of nickel, zinc, and nickel-zinc alloy were investigated by nucleation analysis. A novel deconvolution technique was applied to obtain the individual chronoamperometry of each species and elucidate the nucleation and growth mechanisms of nickel-zinc alloy deposition.

Organocatalytic photoreduction of Zn(ii) to zinc metal

Chemical Communications, 2014
The photoreduction of Zn(II) to Zn metal catalyzed by 8-hydroxyquinoline derivatives is reported. Structure-activity relationships, ideal reaction conditions, and the reaction kinetics are described and a mechanism involving an in situ formed quinolate complex is portrayed.

Hirshfeld Surface Analysis of a Zn(II) Polymer

Координационная химия, 2015
A new Zn-based complex with oxalate, namely [NH2(CH3)2][Zn(Ox)1.5] · DMF · H2O (I) (Ox = oxalate), has been synthesized and structurally characterized. Single-crystal X-ray analysis of compound I reveals that the Ox ligand links the Zn(II) center, generating an intricate 2D classical honeycomb-like architecture (CIF file CCDC no. 1028787).

The sorption of metal ions on silica with covalently grafted propylthioethyleamine groups was studied. Quantitative sorption is observed at ???? 6.5 (Cu), ???? 5.5 (Pb), ???? 7 (Zn and Cd). It was stated that composition of complexes that are formed at the surface is ML (for Zn and Cd) and ML??? (for Cu and Pb). The detection limit obtained by sorption
