A highly pH-sensitive Zn(ii) chemosensor

Dalton Transactions, 2010
Proton and Cu(II), Zn(II), Cd(II) and Pb(II) binding by ligand H(2)L, containing two bis(aminoethyl)amine (dien) units connected by a 2',7'-dichlorofluorescein (DCF) unit has been analyzed by means of potentiometric, UV-vis and fluorescence emission measurements.

The Zn(II)/Zn exchange reaction

Journal of Electroanalytical Chemistry, 1970
Summary The results of an investigation of the kinetics of the Zn(II)/Zn exchange in aqueous electrolytes are reported. Galvanostatic, potentiostatic and faradiac impedance experiments are described. Significant changes in electrode activity occur during the initial 2 h of electrode/electrolyte contact.

Dinucleosidetetraphosphatase inhibition by Zn(II)

Biochemical and Biophysical Research Communications, 1983
Almost complete inhibition of partially purified dinucleoside-tetraphosphatase (EC 3. 6. 1. 17) was observed with 5 microM Zn(II). The inhibition was reversed by EDTA and was time dependent, reaching a maximum after 5 min of incubation at 37 degrees C. Zn(II) behaved as a non-competitive inhibitor of the reaction, leaving unaltered the Km value for the

Directed synthesis of {Cu₂(II)Zn₂(II)} and {Cu₈(II)Zn₈(II)} heterometallic complexes.

Dalton transactions (Cambridge, England : 2003), 2016
Two new heterometallic complexes [Cu2Zn2(H4L)2(CH3COO)2Cl2]·2.5CH3OH·0.5H2O (1) and [Cu8Zn8(OH)8(H4L)8](Cl)2(ClO4)6·16H2O (2) have been synthesised following two different preparative routes, by using the polydentate ligand Bis-tris propane (H6L = 2,2'-(propane-1,3-diyldiimino)bis[2-(hydroxymethyl)propane-1,3-diol]).

Syntheses and Structures of Isoindoline Complexes of Zn(II) and Cu(II):  An Unexpected Trinuclear Zn(II) Complex

Inorganic Chemistry, 2002
Deprotonation of the tridentate isoindoline ligand 1,3-bis[2-(4-methylpyridyl)imino]-isoindoline, 4'-MeLH, and reaction with hydrated zinc(II) perchlorate produces an unexpected trinuclear Zn(II) complex, [Zn(3)(4'-MeL)(4)](ClO(4))(2).5H(2)O (1), whereas reaction with hydrated copper(II) perchlorate in methanol produces the expected mononuclear product,

Ni(II) and Zn(II) perthiocarboxylates

Journal of Inorganic and Nuclear Chemistry, 1971
Abstract The synthesis by Bruni and Levi, modified by Fackler and Coucouvanis, from aldehydes and ammonium polysulfide has been extended to aliphatic aldehydes, and perthiopivalate (CH 3 ) 3 CCSSS − has been prepared. This ligand forms 1:2 Zn(II) and Ni(II) complexes, analogous to the already known complex perthiobenzoates and perthio- p -toluates.

A fluorescent bis(benzoxazole) ligand: Toward binuclear Zn(II)–Zn(ii) assembly

Dalton Transactions, 2010
A bis(benzoxazole) ligand (HL) has been synthesized, and its reaction with Zn(OAc)(2) has led to fluorescent complexes via formation of binuclear Zn(II)-Zn(II) cores. The ligand-to-metal ratio of the complexes varies from 1 : 1 to 2 : 1, depending on the reaction conditions.

Complex species of Zn(II) and Cu(II) in tris buffer solutions—I. Zn(II)

Electrochimica Acta, 1990
Abstract An electrochemical study by means of voltammetric and polarographic methods of complexes formed between Zn(II) and Tris buffer solution has been carried out. The type of complex species in aqueous solutions have been found to depend upon the medium. Details about structure and stability of the species have been obtained.

LHRH interaction with Zn(II) ions

Journal of Inorganic Biochemistry, 1989
Luteinizing hormone-releasing hormone (LHRH), a hypothalamic neurohormone, forms a complex with Zn ions in solution. In order to explain the structure of this complex, the stability constants of Zn(II) complexes of LHRH and also pyroglutamyl-histidine-methylester, N-acetyl-histamine, and N-acetyl-histidine were established with the use of ...
